Rigid Ink Spool Adapter

thingiverse

So I originally only made this an upgrade for my own printer, but by popular demand, I've decided to upload it so everyone can share. The idea is straightforward: I use a lot of Rigid Ink 300g spools with a 50mm inner diameter, but my spool holder is only 30mm in size. To save the hassle of changing the spool holder for each spool, I designed this adapter to make it easy. It comes as one half and needs to be printed twice, but both halves are identical, so that won't cause any problems. You'll also need four 4mm x 1mm rare earth magnets that fit snugly when printed correctly, but may still require a spot of glue to hold them in place (or you can simply glue the two halves together permanently if you have enough space to slip it onto your holder).
