I was utterly mystified with the spool holder that came with the Reprapguru Prusa i3 V2 so I made what I feel is a massive improvement. It will easily print on the Prusa i3's bed. Included is a spindle that measures 50mm across. I may build a few more for the various spool sizes. I hope you find this as a useful upgrade! Note: this bracket requires the extra acrylic rear support to hold it in place. It should be a snug fit that has almost zero play. Enjoy!
Update 2/2/18: Replaced 50mm spool with a corrected file (prior version had an internal artifact that caused some issues) and added a stamp to the end identifying it as 50mm.
Also added a 54mm spool.
