Simple hammer grip/handle for a very tiny hammer.
This is designed to print with rim to protect from warping. This can be printed in 3 parts that need to be friction welded together OR you can print with support and join the two parts anyway you want.
Do not sand away everything, because this hammer grip is not designed with any special pattern to make the grip better. Do sand away unwanted seams from the friction welding process.

Measure of outer and inner diameter of hammer core, printed a 10 mm high test to get a feel for how tight its gonna be.
Im lazy and didnt want to sand away any support, so designed this with friction welding in mind.
