Double Sided Spool Holder for Original Prusa i3

thingiverse

This is my very first modification to my incredibly awesome Original Prusa i3 printer (which, by the way, is a true marvel). My trusty printer has the amazing capability of printing in colour by simply changing the filament during a print. However, I was not entirely thrilled with having to swap out spools because I was worried about knocking the print bed or experiencing other mishaps. So, I created the incredibly handy double-sided spool holder (which perfectly sits between two spools) that allows me to easily mount more than one spool at a time, making it effortless to change filaments and minimizing the likelihood of accidents due to my clumsy attempts. This brilliant modification was adapted from the original STL print part files generously supplied by Prusa Research. Since these files haven't been officially uploaded as a standalone item, I'm not confident in saying it's an actual remix – despite its similarities. I took the initiative to research printing the 'dowel' piece as a flawless cylinder, but then I discovered potential issues with fitting parts together. To resolve this issue, I opted for an octagonal design that would facilitate an effortless press fit. A huge thanks goes out to Make for their valuable tips on the subject (makezine.com/2015/07/22/tips-3d-printing-press-fit-parts). I strongly believe Karlosek's Spool Hole Reduction thing (thingiverse.com/thing:938464) will work seamlessly with the octagonal dowel since it shares the exact same diameter as the original cylindrical part. At this point, I think I've babbled on for long enough, so I'll allow you to take over – if that's what you desire. Feel free to provide any feedback, whether positive or constructive; every contribution counts.
