Printable Groza (Airsoft)

After I 3D printed the front set of the Groza conversion kit from longineus, I decided to also print the rest of the gun...so here it is :)

I have to say that i did not make most of the parts in this project, other ppl here on Thingiverse did.
I still had to make all the parts fit and did some slight improvements to them.
Big should out to longineus for making this even possible because he did most of the work.(he also has a lot of cool attachments for the Groza so check him out)
All the other creators are mentioned as a remix, they also helped immensely.
Sadly I'm not allowed to use the dust cover from TwiggyDesigns as a remix, but I link it here so you can download it from him: https://www.thingiverse.com/thing:3541397

How to Print:

All the parts are printable on a standard ender 3 (220x220x250).
I suggest at least 4 walls and an infill of 30% to 60%.

parts list:

• v3 gearbox
• standart ak hop up
• ~303mm barrel.
• a tube ( with a diameter of 16mm and enough space to fit a standart aeg barrel)
• m3 and m4 heated inserts
• a variety of m3 and m4 cylinder head screws and bolts ranging from 6mm-35mm
• 2x m5 Cylinder head screws and bolts
• 4x m3 countersunk screws with a length of 8-12mm
• 1x m4 threaded rod
• 2x 3x10mm springs
• 1x torsion spring inner diameter 3mm, outer 5.2mm, hight 8mm (i used these

  1x m4 spring washer or loctite
• 1x long spring with a inner diameter of at least 3mm ( I used the one from my old AK that is on the metal rod of the charging handle)
• 1x metal rod with a diameter of 3mm or the metal rod that is connected to the charging
  handle of airsoft ak´s
• 1x very small microswitch
• 1x mosfet (i build one based on the irfz1404 but you can also just buy a commercial one)
• some cables (I used 1,5mm² cables that are used in cars)

assembly:

You should find out how to assemble the groza with no problem.
You might need to file some parts or cut some screws to get the right length.
Use loctite or a spring washer at the screw that holds the motor cage or it might lose itself.
Use the 3x10mm spring at the trigger and the hole at the side of the trunion.
The threaded rod is optional, cut it the right length and put it into the grip.
You NEED to use a mosfet to use the microswitch (DO NOT wire the battery directly to the microswitch or it will blow up if you press it).
You can also wire the microswitch to a etu to get the most performance and more features out of your gun.

testing and tips:

I tested it outdoors and in cqb and it performed very well.
The gun is robust, there are no moving parts or any squeaking noises.
Sadly the gun is pretty loud so you might want to build you gearbox as silent as possible and/or dampen the inside of the gun with foam.
You have enough space for a regular stick type battery.

if you have any questions or suggestions please leave a commend or DM me.

----update 22.05.23------
I added a stronger carry handle because mine broke at the part that connects to the picatinny rail of the trunion.
I also added more tolleranzes so it fits the picatinny rail better.

----update 4.6.23------
I made a front grip for the Groza. check it out: https://www.thingiverse.com/thing:6060911
