A new deAR22 drum mag tower for your favorite AR22.

This zip file contains the F3D file from fusion, STL, and the DeAR22 file set.
Everything you need to print a fully functional drum.

Design is based off the S&W M&P 15-22 magazines and adapted to fit standard AR22s.

Tested with my AR-15 with a conversion bolt and no barrel adapter.
Fed consistently, but without the barrel I can't say if it functions at 100%.

V3 Changes include:
-45 degree angle for better feeding
-Path for the cartridges is now one continuous curve
-No filing needed for the mag catch slot (height extended 0.5mm)
-Slotted both sides and improved aesthetics
-Removed material from the bottom of the dovetail for flat placement in slicers
-Minimal supports needed in this design and print orientation.
-One extra dummy round needed. Total of 15 not including the top and bottom followers.

V3.1 Changes:
Slight decrease in dovetail fitment tightness.
