Yet another Spool Holder for the Prusa i3 MK3. I was intrigued by the roller-based designs for filament spools and decided to create yet another one for the Prusa. This design doesn’t really provide any advantages besides maybe a little less wobble as the rolling is smooth and there is no spool swinging back and forth. Otherwise, it was just the experience of designing and building my own. Material required besides the printed parts: - 2 X 3mm steel rod, 100 mm long (similar to these: https://www.amazon.com/uxcell-100mm-Stainless-Steel-Solid/dp/B082ZP313B/ref=sr_1_3?crid=1IJEFW2BOVR8D&keywords=steel+rod+3mm&qid=1644204132&sprefix=steel+rod+3+mm%2Caps%2C90&sr=8-3 - 12 X M3 Bruss Nuts (similar to these: https://www.amazon.com/Printing-Embedment-Knurled-Automotive-Notebook/dp/B09KZSJS88/ref=sr_1_1_sspa?keywords=m3+insert+brass&qid=1644204228&sprefix=m3+insert+%2Caps%2C87&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUE2VDRKOFQxNDFRWEgmZW5jcnlwdGVkSWQ9QTAzMTQzMzMzR1U2OERRWUVYTDMzJmVuY3J5cHRlZEFkSWQ9QTA5NzY4MzYxV0Y4SDVKREMwMFdPJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== ) Insert the Brass Nuts into the spacer brackets using this technique: https://www.youtube.com/watch?v=KUEFhiFB6Zs&ab_channel=EricYoung - 12 X M3 x14mm (similar to these: https://www.amazon.com/MroMax-Machine-Recessed-Phillips-Stainless/dp/B07YSB398F/ref=sr_1_9?crid=2GG376ONZORD3&keywords=Screws+m3+14mm&qid=1644204652&sprefix=screws+m3+14mm%2Caps%2C109&sr=8-9) 12mm or 16mm length works as well
