Perfect fit for silicone 3D printer boots

This was the first time I made something out of silicone myself. I was a little scared but figured that a single component silicone hose couldn't be too harsh. I printed a mold for my Geeetech A20M OG hotend from Thingiverse and squeezed some of this paste onto it. After about a day (with some heating in between) the mold was ready. I've had the best results "painting" a small amount of dish soap around the shape with a brush. The cured product is flexible and has withstood many hours at 200-240°C, so I'm satisfied.

Pros

Consistent test results

Cons

Annoyed
