Hammer head

This old hammer lost one of its striking surfaces.
This project prints a mold and stem base for a silicone rubber replacement.

I used an RTV silicone rubber (Tinsil 70-60 Polytek) to pour the replacement hammer head.

This is a high tensile strength, dense rubber.
The mold is about 25 ml in volume.

Designed in trueSapce and printed on an Up!3D in ABS from Octave.
