i3 Heater Block Gasket Mold

DO NOT PRINT YET, DIMENSIONS UNVERIFIED I discovered the e3d silicone mold first, then found this printable mold, which inspired me to try it as well. Since my heater block has different dimensions than usual, I created a custom version. I printed the pieces in PLA and filled them with high-temperature silicon gasket maker. Updates will follow with finalized dimensions and more photos. Initially, I bought red gasket maker instead of copper, which is slightly springier but still handles temperatures well. It took around three days for the gasket maker to set completely, as it's not meant to be applied too thickly. You can see in the first picture my second version, which was designed after the initial one. Unfortunately, some parts were too thick, resulting in a subpar outcome. I trimmed it up and now it fits perfectly, but I accidentally cut the top too short, so it doesn't quite meet expectations. With the DIIICooler and MicroSwiss hotend combination, I sometimes had to set my printer 5-15 degrees warmer than necessary because it wouldn't maintain a stable temperature. Now, there's virtually no fluctuation, staying within +/-1 degree most of the time. The second picture demonstrates that even when heated up to operating temperatures, the gasket is safe to touch. It does get hot, but it won't cause any harm. Absolutely safe! Overall, I'm extremely happy with this so far, and new files and pictures will be uploaded soon.
