This is a 1 piece spool holder for standard 1kg spools. This design utilizes injection molded pegboard hooks which provide strength over printed hooks and fits standard pegboards with 1/4 inch holes on 1 inch centers

The design intent here is for the hooks to be inserted from the bottom were they will be wedged in place so they don't fall out. There is a small sacrificial bridge towards the base of the slot, this is just there to make sure the slot doesn't deform during printing and defeats the need for slicer generated supports. Snip it off after printing.

The hooks can be purchased on amazon, QTY 50 for under 10 dollars.

The hook can also be downloaded from https://www.thingiverse.com/thing:4261878 which i modeled off the hook from amazon.

I printed this on a QIDI X-Plus (flashforge clone) using various brands of PLA. Sliced in QIDI's cura clone software with the part oriented so the flattest (bottom) face is on the print bed.
