Bolt Together AR-15 Castle Nut

This is for the AR-15_Bolt_Lower_Receiver_v2.0-RollTroll from the FOSSCAD_MEGA_PACK_v4.8_(Ishikawa).
Once I assembled my rifle I noticed that the castle nut included with my kit would not work with the 3d printed lower due to the buffer tower on the lower being way to thick. To remedy this, I made my own out of ABS.

You will need at least two 8-32x1/2" screws; five is preferred, and two 2-56x1/2" screws.

You must acetone dip (not vapor, but an actual dunk in acetone) to increase strength,
