Replacement Shells for UDL Winchester M1887 foam dart blaster

thingiverse

They work like a charm. Took a while to find the balance between being ejected and having a good amount of power, but I found the sweet spot. Print standing upright, no supports. If you want, change the filament color at 12mm. I use layer height 0,2mm. I usually print 9 in one go. Just slide along the inner hole with a nail scissor to remove loose parts should they appear. I use PLA, PETG might work as well.
