AK Lowcap Magazine (40rd)

See video for assembly instructions:

A very small ~40rd lowcap magazine for airsoft AKs. Tested with E&L AK710 SBR which also fit CYMA mags - so I'd assume anything that works with a CYMA can take these too.

The video shows a different AK magazine but the assembly procedure is the same.

The files ending in ALT are alternative versions of the inner parts and the stopper/retainer. The difference here is that the stopper is slightly larger and may feed better in some guns. I recommend first printing the non-ALT files. If it doesn't feed in your gun then try the ALT files instead. They all use the same shell, baseplate and follower.

Print settings

See image for print orientation. It is necessary to gently sand the top surface of Inner1 and Inner2 to ensure a smooth surface and prevent a gap, 3 seconds of 120 grit sandpaper should suffice.

Recommended print settings

0.2mm layer height, 15% rectilinear infill, 2 perimeters. The outer shell can be printed with 0.3mm layer height to save time. I used a 0.6mm nozzle for everything but 0.4mm should work fine too.

Make sure you avoid underextrusion and print at a reasonably high temperature for the filament to improve durability.

Required parts

2x M3 Nuts, example: https://hobbyking.com/en_us/hex-nuts-m3-10pc.html

2x M3 Screw, 8 to 10mm, Countersunk, example: https://hobbyking.com/en_us/titanium-m3-x-8mm-countersunk-hex-screw-10pcs-bag.html

1x AEG magazine spring (since the mag is so small one spring is likely enough for at least 3 of these mags)

1x Ballpen spring, ~11mm (one spring is enough for 2 magazines)
