Spool for high gauge wire

This is a low filament amount (less than 2m per spool) spool for electrical wire. I bought 0.14mm wire of of amazon and it didin´t have a spool, so I designed this. It´s pretty basic so feel free to remix.

The settings and material to print this don´t really matter.

I´ll probably add an adapter for a drill soon, I already designed one but it doesnt work well enough to publish.

This is a work-in-progress.

Edit 1:
Added Mk2, the same bottom part, but with a different pattern in the core, which reduces bridging. Havent printed it yet but it should work just as well.
