Many of the attachment parts in the Multiboard ecosystem have what is referred to as a "coin slot". As I don't use change (or even paper currency) very much anymore, I don't always have a coin available at the right time. Also, I like a little more torque with a more convenient handle. So I made this... it has a slot sized for a US penny. Fill the slot part-ways with your adhesive of choice, insert a penny, and let it cure. You'll now have a tool for those fussy little bolts and Multipoints.

I printed mine with the same settings as most other Multiboard objects. I did add a fuzzy "voronoi" skin to give it a little better grip. I've included both .stl and .step files in case you need a slightly different coin size.
