Molded Rubber Door Stop (printed mold)
thingiverse
In need of a gray doorstop to protect my refrigerator from dents, I decided to create one using my Thing-o-matic printer. First, I made a negative mold of the desired shape with the 3D printer. Then, I used homemade Sugru substitute, which is a mixture of silicone caulk and corn starch, for forming the doorstop. To avoid air bubbles, I carefully poured the mixture into a rubber glove mold and let it cure in 20 minutes. After obtaining a satisfactory piece, I attached it to my fridge using more Sugru substitute. This DIY project has been holding up well for over a year now.
