AR-15 Bolt Catch Plunger

thingiverse

Here is the rewritten text: The tiny piece that quickly disappears after release, originally known as an itty-bitty part, has been replaced by a new design for the bolt catch on AR 15 and similar rifles. Printing in ABS at 100% infill takes approximately ten to fifteen minutes. A raft and support are highly recommended to ensure optimal results. The photo doesn't fully capture the quality of the printed piece due to the crinkled plastic bag used to contain it, preventing loss. Since the original design dates back to 1964, it is no longer under patent protection, making this digital representation equally unoriginal and in the public domain.
