Flatspin

Unwind filament from a spool lying flat

A low turntable for filament spools: lay the spool flat on the plate, feed the filament up through a guide above the printer, and the ball-bearing base turns as the printer pulls while the rim keeps 200 mm spools centred. Cardboard spools that squeal on rollers unwind smoothly lying down.
