While using my Wallace 8mm version, I noticed the motors occilating up and down. So, I designed a pair of Feet to support the outer edges. After I'd done that I realised I now had a place to attach my favorite Spool hook! So Here it is! Note: While this hook can support all the spools of my previous designs. It will lean over when holding a 2kg roll. 1.5kg or less, no problems.For just the Motor Feet, if you already have a spooling option you like. :) Print: 2 x Motor_Foot 2 x MSpacer Slide Foot over end of motor. use 2 M3 10mm screws and washers on 1 MSpacer and secure motor to Foot. For Intigrated Hook option: Print: 1 x Motor_Foot 1 x Hook_Foot 1 x Hook_Top 2 x MSpacers Attach Hook Top to Hook Foot. Assemble as above. The Hook has to go on the X-idler end. Enjoy.
