The plastic base of my Molho Leone 78520 hole punch broke, but all the metal parts (punching pins, springs, lever) were still in perfect working order. Throwing away a fully working tool because of one cracked plastic part felt wrong, so I redesigned the base from scratch and printed it.
Designed for the Molho Leone 78520. It may fit other punches with the same mechanism, so check the STEP dimensions first.
Print settings
Material: PETG (recommended) or PLA
Layer height: 0.2 mm
Infill: 20–25% gyroid
Walls: 3
Base: organic/tree supports, with the overhang threshold at 20° (only overhangs at 20° or lower get supports), as shown in the photos
Paper stop tab: print it in the orientation shown in the photos. It can also be printed on its side, but then it slides too freely. In the orientation shown, the friction is very close to the original tab.
A small fix that saves a working object from the landfill. 🌱
