Spool holder with rollers

Easy to print and assemble spool rollers suitable for small 750g rolls or 3kg rolls.
I use these in a cabinet below my printers and guide the filament with tubes or just next to the printer. Degreasing and lightly lubing 606zz bearings give a smooth rolling resistance.

With the right length of m6 bolts these can be attached in series with small magnets or you could even use longer m6 rods and make them solid

For one spool you need two holders and 4 rollers + 4x 606 bearings and screws.

Free for non commercial use, if you want this design to sell or whatever just give me a shout and we will work something out together. Will accept beer as payment, im a simple man with simple needs ;)
