This is a retrofit spool-holder design for the Series 1 3D Printer to ease strain on the extruder pulling in filament.

Requirements:

• original Series 1 3DP spool bracket (metal L-bracket) or L-bracket of same dimensions
• two thumbscrews (M3, the ones used on desktop computer cases)
• four M3 screws and nuts (these come with the original bracket)
• two 608 bearings

Assembly:

1. Print all three associated parts: Guide, Roller, and Leg (L-bracket model provided for reference).
2. Remove the original Series 1 spool holder from the metal L-bracket by removing the four screws and nuts from the original spool holder. Save the four screws and nuts for later.
3. Attach the new filament guide in the same way the original spool holder was attached.
4. Press a 608 bearing into both sides of the roller.
5. Screw the L-bracket into your Series 1 3DP with two M3 thumbscrews.
6. Put the roller through your desired filament spool and sandwich the roller between the filament guide and supporting leg (Refer to provided images).
7. Set the supporting leg down on top of the thumbscrew.
8. Done!
