The cheapest parts kit build. Resin printed Jennings j22
Posted by akdaddy545@reddit | GunnitRust | View on Reddit | 60 comments
Feel free to ask questions. I designed this a while back but it wouldn't work in fdma. I tried it in resin and it held up better than expected. Still broke after around 50 rounds and was unreliable as hell (light strikes, and failure to eject, common Jennings j22 problems) but it's actually happening. The goal was to make the cheapest parts kit build out there. It's my greatest goal to prove that technology has evolved beyond the laws created by those who wish to control who can be armed.
B&t tp9 project is complete but I need to fix my printer again. Go figure.

Why wouldn't it work with FDM?
I'm kinda surprised the resin lasted that long
akdaddy545@reddit (OP)
The material around the barrel failed almost every time during assembly in fdm. My printer was also beginning it's journey into under extrusion issues I haven't had the time to figure out.

Id like a 25 acp version of this please!
Practical-Nerve-1366@reddit
Looks like it came out great. Impressive print quality, even if it is a resin print. I downloaded the STL files for a friend and ordered him the parts, but the STL was way off and I'm not sure why. It wasn't a scaling issue, because even when scaled on one axis to another (or two or 3) the parts never worked or fit. Had to spend days working on the STL in 3DB for him to finally be able to fit and work the parts.
I wondered if there was a different set of parts, like how they had the J-22 and the JA-22 and also the different versions of the J-22 with the rotating safeties. I'm not sure if I got the right parts, even though they specifically said J22 on them and have the sliding safety too (and not the rotating safety). They're the right model, but they just don't fit (not even close). Every single dimension was off, from the barrel center/outer, the grip panels, grip screw holes, the safety cutout, the disconnector cutout, the trigger internal cutout, the trigger pin, etc... etc...
Was hoping to find a new, good version of the files, but haven't been able to find them anywhere. Heard of another person that fixed and uploaded the file for the J22, but when I went to his reddit account it was suspended. Was hoping someone else or somewhere else had his files hosted.
akdaddy545@reddit (OP)
That was me as well, I kinda got suspended. Shoot me a message and I'll send you the updated files. It's a much more reliable reinforced version with just a few dimension tweaks.
Willing_Rub_8860@reddit
Will it work for the 25 acp barrel?
inserttext1@reddit
Damn man, I love pocket pistol builds, I wish you luck.
akdaddy545@reddit (OP)
Most of it is making a standard Jennings reliable and adding as much material as possible. Makarov is next. So many people said it can't happen.
Mammoth-Wrangler6969@reddit
So I know this was a while ago but did you try printing this in Esun PLA plus? Have you made any progress on it?
akdaddy545@reddit (OP)
The Jennings is in open beta and has exceeded 500rds without failure. Might release it soon.
NewOrthoChristian@reddit
I know it's been a while but please do if you haven't yet
akdaddy545@reddit (OP)
Send me a pm. Beta is still open. Not many people get back to me on how their build turns out.
EstablishmentIll512@reddit
could you add me too please i sent a pm
extraweb1@reddit
I will get back to you and this reddit if i could only ge the files
Dazzling-Victory4884@reddit
Could you sell me the internal parts kit?
eddie51211@reddit
Nice bro 👌🏽💪🏽
Dazzling-Victory4884@reddit
Hola, podrías hacer la corredera y las demás piezas para imprimir?
extraweb1@reddit
Did ya ever get stl's out for downloading
akdaddy545@reddit (OP)
You can have them if you pm me
Rare-Worth-4975@reddit
You still have the files? Should have reached out but I ended up interested in your picture and made a decision I should have texted you before making and have a whole kit sitting here waiting for its frame😁😂🤦♂️
akdaddy545@reddit (OP)
Pm me
SaVvDaDoN850@reddit
I pmed you
Rare-Worth-4975@reddit
Much Appreciated
extraweb1@reddit
I PMed you
extraweb1@reddit
I'll post pics as soon as i get the files and print it.
Several-Security-227@reddit
This is badass man I was wanting to attempt this but couldn't find files
akdaddy545@reddit (OP)
There's a new update in beta
Puzzleheaded-Cap4105@reddit
Where’s the beta? I’ve done the one in the sea
akdaddy545@reddit (OP)
You found it.
Puzzleheaded-Cap4105@reddit
Oh 😆 I thought there was another one out. I had tried with grip down rail up but ended cracking on the barrel portion once I inserted the barrel. So I reprint 180° barrel pointing up and seems sturdy but haven’t tried it yet and also saw a pic posted on twister that drdeath put up but looks different.
akdaddy545@reddit (OP)
I'm pretty sure there's a similar print from black lotus coalition
Puzzleheaded-Cap4105@reddit
I’ll try to look it up. I’ve been trying to mess with the design to add an extended grip since I was able to get a 10rd magazine from Taurus tp22 to work. Also been trying to figure out how to make a fdm extendo
akdaddy545@reddit (OP)
Oh then definitely send me a pm before you waste your time. New version is much stronger
Rare-Worth-4975@reddit
You have the stl file for j22?
Puzzleheaded-Cap4105@reddit
so I still got some more range time to go but the beta definitely seams stronger there was some things i had to do to the kits since most of then were mushroomed in the breach face causing feeding and ejection issues and others were missing pins but nothing a Dremel and filling sand paper cant fix also had to add some filament to the feed ramp with a solder iron and left over filament to help with the bullet pointing up (opposite of nose dive) and also did a slight crowning just like the sig p322 to help guide different types of bullets hp,sp or coned ill see if i can post a video to show how it has definitely improved the infamous calwestco reliability lol still working on making some fdm mags and like I mentioned before i got a 10 rd mag to work but not sure if extending the grip or just making a sleeve
akdaddy545@reddit (OP)
Thats awesome! You're one of the very few people to actually follow up on their builds. Let me know what areas need improvement and I'll jump right on it.
Puzzleheaded-Cap4105@reddit
Sending pm for my updates
Brrrrrrttttt@reddit
Is this sailing? ⛵️
akdaddy545@reddit (OP)
Original frame is. Updated stronger version is coming soon. If you have parts pm me
Individual-Leg2977@reddit
Love your work and motivation behind it I completely and whole heartedly agree with you. Our government is getting too out of control with their nazi regime like requirements
akdaddy545@reddit (OP)
Let's openly talk about how much we hate the government and think everyone should have access to firearms right after a 3d printed gun was used in a shooting, and let's make it be our very first comment on Reddit with a zero karma account.
Direct_Syrup_2843@reddit
Seeing this 2 months late shaking my head & wondering why this user hasn't deleted their comment when they've had 2 months.... I swear alot of these comments are just anti 2A trolls attempting to make the communities of people exercising their 2A rights appear as being looney tunes or "dangerous". Im all for free speech but often feel that in places like this that are frequently under attack by those who wish to strip away constitutional rights & liberties, these types of comments should be deleted by mods so they cannot potentially be used as 'ammo' in smear campaigns by the mainstream media or any other anti 2A agencies when they make the decidision to go on a screenshot spree so they have photos to post that paint people who are simply exercising their rights in a creative way in a bad light.
But, my apologies, tangent aside, great work dude! I've been seeing these parts kits popping up more frequently and decided to do some research on reddit which brought me to your post! I have done injection molding using resin, and have done plain ol resin casting with silicone molds for over a decade, which i am sure is probably a much different process, but I am not too familiar with the process of resin printing, or what type of resin is used compared to the resin I use, but I am definitely going to be looking into it after seeing this post!
Awesome work dude. I love the way this project looks and wish you the best on your progress & future projects 👌🏆
akdaddy545@reddit (OP)
To be as clear as possible I use resin as a proof of concept and to find the weak points of prints. If you drop this frame while assembled it'll break. It's functional resin printed but for longevity and safety it should be fdm printed.
Yeah a lot of those comments look really bad printed out on an interrogation table.
I'll be coming up with a readme and posting a final updated frame here shortly. The design is complete I'm just terrible at getting the assembly instructions and intricacies of the seat mechanism and sloppy at best tolerances for the original parts and the troubleshooting that caused all on the readme.
Dazzling-Victory4884@reddit
Could you get me the stl file?
Dazzling-Victory4884@reddit
Me podrías conseguir el archivo stl?
Smart-Western4945@reddit
GOT UPDATED ?ND WHERE THE CHEAP KITS AT ?
akdaddy545@reddit (OP)
There's an update. Pm me
CooperD2319@reddit
Where do I get the files?
akdaddy545@reddit (OP)
Send me a pm. New upload to the sea coming by Monday
Early-Translator7952@reddit
Was this made using good old PLA or PLA +?
akdaddy545@reddit (OP)
No but it can be and has been
Economy-Historian501@reddit
I’m thinking it might be a better idea to make a mold with the plastic 3d print then the frame it made of brass or cast iron from that mold
akdaddy545@reddit (OP)
Brass might not be a bad idea. Might give it a shot
Marlonius@reddit
"I'll improve this trash!" - you, with a lot of time on your hands. Very cool, if odd choice of projects. Why?
akdaddy545@reddit (OP)
Because it was cheap and not really all that much time.
Practical-Nerve-1366@reddit
Yeah, it's a build you can make with less than $40 worth of parts and material. On top of that, these firearms are well designed as far as the magazine location and feed ramp... so when they were manufactured correctly they worked. People had some really unreliable guns, but it was usually the rough edges that were to blame and not the design. Most people could get them to function reliably with just a little finish work. Anyways, I really appreciate you taking the time on this and to make it available. I really hope for the Sterling model too if you ever finished it. (I tried looking for the J22 before and also the Sterling, but didn't find them anywhere... and then found this today out of nowhere when I wasn't able to find it before). Thank you.
akdaddy545@reddit (OP)
Pm me.
IcycleStocks@reddit
Releasing this anytime soon? This would be an amazing for build for me.
TeetheCat@reddit
Ak could I get the stl or is it on the sea somewhere? I actually have a j22 and would love to play with printing out a frame. Ty!
Realistic_Scale2954@reddit
How can I get this Jennings 3D printed frame??
