Filament Guide and Improved Spool Holders for Original Prusa i3 MK2(S)

thingiverse

I had a few issues with the original spool holders, which led me to redesign them. They were too short to properly hold eSun spools, causing one of the spools to fall on occasion. The absence of a filament guide meant that the filament would sometimes get out of the spool and tangle. Furthermore, the excessively tight fit to the printer frame resulted in mine breaking four times, requiring me to super glue it. I aimed to keep the original idea while solving these issues. Printer: Original Prusa i3 MK2 Print Settings Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Notes: The spool holders can be printed laying down without issues, but the filament guide is a bit tricky. The best position to print this part is upside down, possibly it will work without support using PLA. I printed mine with ABS, which wraps a lot and doesn't play well with this geometry. To overcome this, I split the part at the arm junction with the guide and printed the guide upside down, then glued both parts together. How I Designed This I measured spool sizes that I had (eSun, Prusa 1KG PLA, and another local brand). To comfortably fit both the spool and the guide, I extended the arm of the holders. I took special care to ensure a proper fitting of the parts to the frame, making them stable but easy to put on and off. The filament guide has a tighter fit, but not excessive, as there's limited space between the frame and the extruder. This ensures it won't easily move. Oh yeah, and no sharp edges – all rounded.
