Axle for Spool Holder

thingiverse

This is replacement (two-piece) axle that will allow you to load Dremel spools onto the original spool holder. Please note this is the axle only. You will still need to print the base from the original design at https://www.thingiverse.com/thing:3823334 . At a minimum you will need one each of Dremel-Axle1 and Dremel-Axle2. The skinnier axle (Dremel-Axle2) inserts into the larger piece (Dremel-Axle1). This remix includes a "spacer" which is optional. If you use them, you will need two of them. Place one on each side of the Dremel spool along the assembled axle. Because the Dremel spools are narrower, the spool will slide back and forth on the longer axle without the spacers. Dremel-Axle2 should be printed at 80-100% infill, as it is small and under a fair amount of stress. I printed the larger axle at 50%. And the inserts are likely OK at 20% or less, as they do not have to withstand much load. I have a Dremel 3D45 and a couple of non-Dremel printers. 95% of the time I use this spool holder as the source to wind generic filament onto Dremel spools and it works great for that. But occasionally I want to use a Dremel spool as the source, not the destination. Either to rewind a tangled spool, or sometimes using Dremel filament in a non-Dremel printer. The Dremel spools have a much smaller spindle hole than most other brands. This means the original axle on this spool holder is too large to fit through the Dremel spindle. This remix addresses that issue for users of the Dremel brand filament. These were designed in OpenScad, and I included the source files, so you can tweak it how you like.
