Also known as the itty-bitty part that loses itself almost instantly. Created as a replacement for the pin-like plunger that applies spring pressure to the bolt catch on the AR 15 and similar rifles.
Printing in ABS at 100% infill takes 10-15 minutes. :) Raft and support recommended.
The photo doesn't do it justice due to the crinkled plastic bag I placed the part in to keep from losing it.
As the original part was designed in 1964, it's out of patent and this digital representation is likewise unoriginal and in the public domain.
