A custom multiboard holder designed for a full-size 60m spool of Vinymo No 5 thread used for leathercraft and other hand sewn projects. The internal diameter of the platform is 67.5 mm. To ensure a strong but easily removable hold, 9mm Small Thread, Flat Head, T-Bolt screws are utilized and two have been included on the 3mf print profile. I also strongly recommend using a multiboard multitool to install or remove the screws easily.

If downloading the stl directly, the only critical parameter is that this piece should be printed face up to maximize holding strength without requiring supports.
