Useful

this is a great design but it would be better with a slit of some kind in the centre to help retain one end of the strip. a lot of the spools these strips ship on have it and it is quite useful
ended up making this myself, thank you so much for including the fusion 360 file. makes remixing so much easier https://www.printables.com/model/586968-led-strip-spool-holder-with-gap
