8mm Rod Spool Holder

I realised I had some 8mm steel rods left over from another project, and figured I'd use them for a simple spool holder. Made in Onshape to fit on the A1 Mini's printbed, out of PETG for convenience but PLA should work fine. Not huge clearance with some spools, so you may wish to mount them on the underside of a shelf if that suits your setup.
