Simple 3d printable wrench for FAL. I designed it so most of the stress would be taken by the steel parts to help increase its max torque. This can be made with only a hacksaw, file, drill, and 3d printer.
Press Tooling for the Groza I designed.
1.) For max strength print these parts so that the layer line is perpendicular to the centerline barrel while in use.
>You may be able to get away with printing with the layer lines running parallel to the barrel axis provided you have good layer adhesion, and have a light press fit.
>Use 100% infill (or greater if you have the settings tuned to do so).
2.) I recommend using PLA or PLA+, I have used PLA and it worked fine for me
3.) Make sure to support the block as much as possible while in use
>This means having something like the plates under it I used a homemade version of the two steel bars in this: https://ak-builder.com/index.php?dispatch=products.view&product_id=29978 (ak barrel press tools).
>This part may deform/indent where it contacts the part this is OK.
4.) These parts are designed for PLASTIC.
>Be careful if you decide to make a aluminum or steel version as the dimensions may need to be changed to suit the material and to not damage the barrel components
Print with 100% infill.
Make sure when using the the barrel pin pressing block, to clamp both sides to prevent rotation. I used 2 aluminum plates and a C-clamp to do this.
I modeled this to practice using Fusion360, it is based off of HMG Cetme L bending jig. The mandrel is made from steel and the die is made from aluminum. You might even be able to 3d print, but do so at your own risk. You will also need 2 bolts, 8 washers, and 2 nuts to use the jig. Good luck and have fun with it.
Some 3d printable drilling jigs I designed, details about making and assembling the jig are in the readme file. These can be used for RPK and AK recievers to drill the rivet holes, it is not compatible with Chinese ak trunnions , or ak74/22mm trunnions. I will release a ak74 version at a later date.
Update 7/16/22: Revised the documentation
Quick video on how I set up my side sling swivel.
Stuff I used:
Electrical tape
1 3/4" Knipex Pliers Wrench (Channel-Locks will work too, but make sure to use a generous amount of electrical tape on the jaws to prevent scratching)
Shims made from a drink/soda can
Large Shim = 17mm x 34.5mm
Small Shim = 17mm x 14.5mm
These dimensions are loose, you may need to change the size for different manufacturers (cage codes) of sling mounts
Side sling swivel (I used a CAGE 83005 mount)
Commonly used sling mount cage codes
83004 (Wilson JG Corp THE)
13629 (COLT)

I hope this video helps anyone trying to make these magazines. This is my first attempt at making a video, hopefully it isn't that bad.

Video I made on installing your upper parts kit, and a super easy way I found to install your dust cover c-clip without it flying across the room, forcing you to buy another one, which will cause you to wait a few days. In those few days you will be wondering, why didn't I watch this video, why did I fail to consume this brilliant (wildly autistic) content, and where was this video when my life when my wife left me for spending $20k on dust cover c-clips only to fail to successfully install a single one.

I Modeled this a while ago, and uploaded it on a forum. I uploaded it here to make it a bit more accessible. Below is the description I had on my original forum post. Unfortunately I don't have the STEP file, if you are able to get the step file, let me know and I can update the file.
I had some time to kill and I wanted to get some practice in with fusion 360, so I modeled a bullet guide for the yugo m76 (8mm ak). I took the dimensions from a new m76 bullet guide that I bought off of ak files, and from the blueprints in the ak TDP. If your going to make this I would undersize the hole so that you can drill it when you are going to rivet it to the trunnion/receiver. Also something to note is that is the m76 bullet guide is thicker than a standard ak bullet guide, so that if you want the correct guide you will probably have to make it from scratch. Additionally I would double check the location of the "dimples" on the edge of the bullet guide, as I had a hard time trying to take measurements of those from the bullet guide I have, I don't think that locating them is critical to the function of the rifle as long as they clear the 8mm tips.
