Rust inspired airsoft CM.045 mod

This is my mod for the CM.045 airsoft AEG.
The stock requires the purcharse of a shovel handle for a 38mm shaft.
The following parts need to be printed:
-Lower handguard: lower_handguard.stl
-Upper handguard: Either upper_handguard.stl (as one part) OR upper_handguard_main.stl and upper_handguard_shaft.stl
-Pistol grip: Either pistol_grip_cracked.stl OR pistol_grip_clean.stl, depending if you want the cracks.
-Stock: stock_adapter.stl

All parts except for the upper handguard should be printed in the stl orientation, some require supports (touching buildplate). The upper handguard should be printed flat on the wide face and the shaft vertically for better quality.

I used wood filler on all the parts and used this technique for the wood effect: https://www.youtube.com/watch?v=CIZZfzCVmLo
