Nerf Trilogy Shell for Brass 17/32" inserts

thingiverse

This is a remix from the following Design: https://www.thingiverse.com/thing:4530305 Somehow the size was just slightly to thin and the shells would not hold in the rear of the Trilogy. Also this one is designed and tested for 17/32" brassing in order to get the sweet 100fps out of the trilogy with AR removal and 13KG+ spring. Brass can be friction fit just fine, no need to glue or tape. Printed with Supports, at least ABS required it for the Letters. Print upward, not laying sideways. Print with initial layer width 120% -130%. This will allow for a tighter end seal. Leave the brass tube lips slightly protrude by 0.2mm~ at the bottom for a better air seal to the soft rubber on the plunger. Press fit your brass tubes from the bottom up. Can be printed as low as 1.0 Resolution but since it's ABS on mine i just print in 0.2 and cure it with Aceton to smooth the outside.
