Park Tool Hammer Head HMR-2 and HMR-4
thingiverse
These are replacement hammer heads for Park Tool's HMR-2 and HMR-4 hammers. I printed mine in tpu with 100% infill and they worked great but feel free to print them in whatever you like and see how it holds up. The HMR-2 is designed to have a 16mm long, 10x1.5 bolt embedded mid print. I will eventually do a better write up but a quick run down on how to do that is in my IG reel: https://www.instagram.com/p/Cod-QBdImbi/ The HMR-4 has the threads built in and can be printed directly as is.
