Gridfinity Solder spool holder 2x1

I liked this model but I wanted something to lock the spindle in place.I designed this from scratch basing it on the work of the model linked, but I consider it a remix - it's only fair.The spool is locked in the holder by two end caps that expand when pressed into the spindle. Max/min spool dimensions that will fit:Max width: 30mmMax outer diameter: 65mmMin inner diameter (hole): 15mmPrinted in Bambu Translucent PETG + one of the caps in PLA Basic Black for the fun of it. Should print fine fully with either PLA/PETG.
