What an odd coincidence! I have just this evening finished the drawings for a device I have invented and will be taking to the local University Technology dept to have a 3D copy rendered. Unfortunately, the finished product will need to be made of an elastomer and all the University can make are ABS prototypes. BUT, injection molding will be used to produce scads of the thing, so the ABS can make the negative mold for the injection process.
We’ve got a couple vendors close by who would be happy to print in silicone rubber.
I have room temperature silicone compound
Send me the drawing
FYI...... food for thought
