I found it difficult to make a trace around my items using the Shaper Trace from the company Shaper. So, I designed a penholder that in my opinion make it a bit easier to do the traces.

I designed it in two parts, so it should be easy to print without overhangs. However, to avoid loose items, I've intentionally made this very snug and therefore it's very likely that you will need sand a tiny bit or remove a tiny amount with a knife where the base and main part goes together.

Also, not that this was designed for the pencil that comes with the shaper trace and I haven't tried any other pencil.
