Based on the "Curl-A-Dog" device that spiral cuts a hot dog before grilling.
Accepts a 3mm, or 1/8", skewer through center. (Hole is 4mm)
Works on bun length hotdogs.
Made in food-safe PLA.
cutting section is one extrusion thick, so check your thin wall print settings.
Hinge is a 3.1mm hole that I inserted a piece of 3mm filament (2.85mm) throughout. Fit is nice, but make sure you do not use supports.
Both sides are the same file. You can print both at same time if you choose, as I did in the picture.
After folding and cutting the hotdog, then place the metal (or 1/8" bamboo) skewer through the holes. This will allow easy removal for grilling.
Heated glass bed.
