I lost my favorite pizza cutter I had since college... I drew this up from memory!
No, it just isn't the same, but this works just as good.
Step 1: Print the Parts
Download and print the parts in the orientation shown.
Blade and Plug should be 50% infill. I like as high of a resolution as possible to help out with layer adhesion.
All files can be printed without support material!
For me, I used ABS for this part. You can use food safe material, but ABS seems to be working well.
Step 2: Assemble
Everything can be assembles without adhesive.
The plug should fit into the hole of the blade, and the housing will press-fit over the blade assembly and hold it all together.
Step 3: Take Pizza Out of Oven... That's It!
This is made to be disassembled for cleaning. Depending on the plastic, it should be top-shelf dishwasher safe.
I've used ABS and have had no issues so far.
