Thumper - Picatinny Rail

This is a slide replacement for the Thumper, which adds a Picatinny rail at the top. This is to complement the Silly Shell adapter for the Thumper - https://www.printables.com/model/1424465-thumper-silly-shell-adapter-clip

It uses five M3 heatset inserts (5mm OD, 3.5 or 4mm depth) and five M3x10mm bolts.

Also included are the 4 shell Picatinny carriers from Sillybutts, which I have slightly trimmed off the tabs on the insides of the clips and made them smooth.  The shell carriers need four M3x30mm bolts and four M3 nuts.

The tabs were gripping too tight, and were even marking the shells.

Also the recess for the nut is pretty tight, I have found that you will have to use the same heatset tool to melt the plastic and press them in, as you would with the heatset inserts.
