About this 3D model
I redesigned it so it will not twist as much and is a bit less bowy between the wood rails. I left a hold going through this spool holder so you can if you want to add a 1/4 20 rod, nut and a couple of big washers to beef it up some. I don't think you will need to , but it is there. FYI this is one of my first prints on the cr10 S4 I tryed speeding up the printer on this one and the print quality is really really bad
