a thing to sort harbor freight punches, with a little tray for some reason. does not retain punches, just holds them in order from largest to smallest. takes about an hour to print(.2 layers, 13% infill, on my fast voron trident profile) , no supports necessary. harbor freight quality control being what it is you may have to scale or drill out the holes to fit. i based this model off the set i bought, your millage may vary.
