Rail Spike - A 40Max-compatible blaster - some tweaks

First up, thanks to Domochevsky for releasing this blaster AND the step files!

Secondly, the parts here use M3 heat set inserts (5mm OD, 3-3.5mm height). Don't use any smaller ones, they will fall out or not be strong enough.

On to the mods…

Barrel

- Thickened the top of the barrel and added three M3 heatset inserts, so that you can add a Picatinny rail (model also included)

- Made a split pin which needs a heatset insert and a M3x20mm bolt to connect the barrel to the main grip body (replaces barrel-axis-v2.stl) 

- Thickened the areas around these pivot holes

Barrel lock

- Adjusted the tolerences for the channel that the barrel lock rides on, so that it slides more freely. Also trimmed these latches so they catch better.

- Added threaded insert holes for the finger grips, you can then add a bolt or the included finger paddles to make them easier to push

Safety muzzle

- Added a loop where you can attach a sling

- Thickened the barrel to make it easier to print

Trigger

- Made the finger recess slightly curved like traditional triggers, also made it slightly narrower, as mine would bind in the grip piece

All in all, I had a lot of fun modding my blaster, hopefully these files will be useful for others.
