Files and build instructions for the #BitcoinSpaceHeater see https://twitter.com/NakamotoHeating/ to learn more.
- Create a space heating solution based on an Antminer S9 which is completely or near silent.
- Reuse existing parts of a stock S9
- Use parts that are easily and widely available or are 3D printed
- Simple and low complex solution. Goal for anybody to build this at home
- Completely Open Source
The injector plates are designed by @Adrian_van_Wijk. And freely available under the stl and stp Folder.
We strongly suggest to print them with ABS, as PLA get malleable (glass transition temperature) at 60C/140F which could cause problems when the Oil gets to 60C+ temperatures.
Experience shows that the threads and pipe of the bottom cover are better printed without support. For this there are 3mf files attached that have the required support inhibitors and settings for an Ender 3V2 printer with ABS (modify to your needs).
