Maruzen M1100 - Improved Shell Set - Airsoft - Free Download

Unlock the potential of your Maruzen M1100 by using 3D printed shells out of TPU.
The strong layed adhesion of TPU will prevent the shell rim being ripped off when cycling, while at the same time reducing wear of your "almost museum piece of an airsoft". 

In testing I found it to be more efficient, to have extra models for lower BB loads, than to "underload" a shell that could fit more BBs.
So I made them available in different sizes, 1 BB up to 9 BBs.
Recommended BB-count and BB weights are writen on the shells itself.
Just choose the shell size of your liking and get to printing. 

I found a seal design, that will retain your BBs in the shell, while not reducing your energy.
Gloss TPU (95a) is needed for the seals. If you follow my Print Settings, the seals will provide consistent power, not distinguishable from OEM shells.

Please remember that this platform is still a bit finicky, shells alone wont fix issues that may persist already ;)
