Vitamin Free-ish 73mm Spool Roller
Description
I Never Found A Spool Roller For The Seemingly Quite Common 73Mm Wide (68Mm At Center Of Walls) Spools That Companies Like Protoparadigm And Makerbot Sell, So I Decided To Make My Own. This Spool Roller Allows Standard 608Zz Roller Bearings To Be Snapped In And Stay Secured Without Any Additional Hardware. Enjoy!
