Horizontal Low Profile Spool Holder w/ Filament Guide

Couldn't find any spool holders that take less space, wouldn't affect operations, and still being able to be mounted on to the frame, hence I decided to design my own.

I have tested out on a few prints, it may not be the smoothest, but it has no adverse effects on print quality.

Do let me know if you face any issues, and I will try my best to assist.
 

Disclaimer

• Do note subject build is a prototype. I have some plans to improve the design, and also to include different rod sizes to fit different spool types.
• **The filament guide may cause noise during extrusion when tension is increased by the extruder, causing the tensioned filament to scrape against the filament guide, generating a loud screech. You can reduce this effect by placing the spool closer to the left axis, thus putting less strain and less noise is produced.

Designed in reference

• Designed using 1.75mm filament, 1kg spool, Prusa I3 MK3S+.
• Part designed in Solidworks and prototype sliced in Prusaslicer
• If you are printing this for other models/printers, please do check for compatibility.

Printing guidelines

• Any materials
• 15% infill or above
• Perimeters min. 2
• layer height 0.2 - 0.3mm
• No supports needed
• **Prototype was printed in 0.3mm layer height, 5% infill with PLA and PETG. No deformities was observed.

Slicing

• Orientate parts so there's no overhang. 
• Print spool holder body with the honeycomb side down.
• Print knob with the flat side down.
• Do check for the correct side of the spool disk, as one of the sides contains a step.
• Note: Spool holder body cross locking extrusion and tail radius may have some droops due to the bridging. However, it will not cause any fitting issues. I will be updating the cross locking design into a hexagon in the near future to fix this. 

Assembly

• Assemble spool disk onto the body. the top surface of the 2 joint parts should be flush with no protrusions. 
• Use the cross pattern on the knob to secure and lock the assembly.
  
   

Happy printing!
