This is a multiboard version of the modular wire spool holder. It is inspired by this model.

It snaps in the multiboard using Push-Fits. You need to have a Multiboard Snap to attach it to the board: https://www.multiboard.io/parts-library/snaps

It needs supports for the push-fit in the back only. There is a builtin support that needs to be cut with an exacto knife in the front wire slot.

It is compatible with the original spools from the original model, but you can also use my redesigned threaded spools to go with it. It is a redesign to remove the need for screws or glue.
