Printing Parts are pre-oriented and with supports included. Choose the 230mm version (230mm thick spools) if you can print 246mm tall pieces, otherwise choose the 190mm version (prints 206mm tall)

Parts to print:

• 1 roller (230mm or 190mm)
• 2 connectors (same size as roller)
• 1 roller cap
• 2 sides

Recommended stronger than normal settings. Perhaps 3-4 perimeters/walls, at least 20% cubic or grid infill. The roller and cap are the most sensitive parts. I printed in Fiberlogy Vertigo PETG. I print at the higher end of the recommended temperature range for better layer adhesion. To avoid roller seam, I suggest printing the roller separately with random seam position.

Assembly Requires no screws, but is a bit tricky to assemble and can use some help from a second person. Screw in the connectors to one side without tightening. Hold the second side at the other end of the connectors. Unscrew the two connectors while continuing to hold the sides at the ends of the connectors. Screw in the two connectors at the same time to both sides and gently tighten. Spool holder is now assembled. Screw the roller cap into the roller. Place the roller on top of the spool holder. it should rotate easily. Make sure it's centered. For heavy spools, use a bit of grease at the contact points.

Handle with care and avoid shocks or dropping heavy spools on it. For direct-drive extruder use a reverse Bowden tube (PTFE) connected to the 3D printer frame to avoid jerk.
