UPDATE: V2 has been uploaded, the original had a scaling issue and I uploaded the wrong file. If you want to offset the position of your spool, but still use a spool holder designed to fit the exiting mount holes, this simply hooks on the back or side of the body. I wanted it for mounting larger diameter spools without the risk on interference with the cables etc. Also Featured in these photos Robert's Low Friction Spool Holder https://www.youmagine.com/designs/low-friction-um2-spoolholder
