Spoolholder for tabletop mounting

This is the spoolholder I designed for the Ikea Lack enclosures I built for my Prusa i3 MK3 printers. Worked fine both with the small 300g PETG spools which came with the MK3S upgrade kit, and with the 2kg spools from Plasty Mladeč (and basically with anything in between)

Note: this design is quite an old one. Back then I didn't know how to orient STL files properly. I suggest printing the "holder" components with the flat side on the heatbed, and the rollers in the upright position - you might want to add a brim to it, although I printed them without one (on a Prusa i3 MK3 with a powder coated sheet)
