Sprue

thingiverse

This model is so embarrassingly simple I almost didn't share it. I've been experimenting with silicone mold making and as part of that I found myself needing sprues. I designed this model with the idea of being able to have an easy to print re-useable sprue at my disposal. I've been using these with a dab of cyanoacrylate type glue. They have so far been able to be reused between castings. One side is flat to make them easier to print. There is a small point at one end to make the contact point with your molded part a bit smaller.
