Diameter hole size: 4ishDiameter inside bottom of spool 26mm. Diameter mid-height spool around 32mm.Fits these: https://www.amazon.co.uk/gp/aw/d/B00J7MKAHA?psc=1&ref=ppx_pop_mob_b_asin_titlePrinted with 0.3mm layer height in PLA with 0.6mm nozzle.Print with hole facing up. If the hole is too tight to fit onto the pin of your machine, you can always make it larger in the model, or use a 4mm drill bit and widen it out a bit. No more wobble for those nice big cheap thread spools. Make sure the 3 pins fit the holes when inserting (I just align it a bit and then wiggle until it falls into place, then press down with my finger to fix in place). To remove, poke with your finger or a pen from the bottom.
