Easy Spool Holder - Spool Safety Lock with Stoppers (Prusa MK2 / MK2S)

Petclaud did a great job remixing IsmaelPR1's spool holder and even included a spool lock. I wanted to use the spool lock for the cardboard spools because I'm always worried they'll fall over. Unfortunately his is too short for my spools so I made a longer version. I also added some holes to place a stopper that limits the spool's travel and prevents it from falling over.
