A new deAR22 drum mag tower for the Smith & Wesson M&P 15-22.

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.

V3 Changes:
- 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:
- Less tight dovetail fitment.
- Filleted bottom front end for allowing use with milspec lowers with a magwell clip.

V3.2 Changes:
- Shaved material off the top of the dovetail, preventing fitment in milspec lowers using clip adapter.

V3.4 Changes:
- Gave the feed lips a few degrees of tilt for better feeding, and rounded the front for clearance with the feed ramp.
- Beefed up the feed lips for extra durability and longevity.
