A friend from Thingiverses sent me this, was told I could share it.
He said he glued the pieces together with JB Weld plastic weld (JBWeld 2 part Plastic
...Plus Bonder), power sanded, then painted.
Printed with 8 shells, 15% infill, with supports where needed
It appears it may be a remix of the MAXIS MK II stock (verifying)
