AR 15 Lower Vise Holder

Wanted to true my AR15 scope so I designed this adapter. The main goal was to produce ramp with exact angle of mag well.
One end goes to mag well, the other is held by vice. Do not forget to push the mag release before you push the adapter fully in.

I printed two instances of the part, one mirrored around x axis. Also flipped both halves 90 degrees around x axis to lay them flat. Little holes are there for short pieces of 1.75 mm filament to key the parts while being glued together.
