Prusa i3 MK2 Spool Holder

thingiverse

I liked Mirkoengineer's spool holder design a lot, but my main concern was the filament roll being pulled to the left and potentially falling off. To address this issue, I added an extra arm on the left side to keep it securely in place. The only change made to the original design is the addition of this new arm - everything else remains unchanged, including the fillets.
