Multiboard double pronged hook for hammer. (Or other similar shaped items)

It fits into the Big thread section of the board with a big thread bolt.

Any big thread bolt on the multiboard site will work. I have included a remixed version of the 9mm Big head flat head bolt with a coin slot so you can tighten it with a coin.

I have a more robust, slightly larger, upgraded, V2 version here. (30g print compared to this 19g print)

Need something similar for small objects? look here.
