How to FDM Print for Part Sliding Clearance

13 4 Intermediate
If you are 3D printing parts that have to fit/slide together after printing, you will need to put some sort of clearance between those parts in your CAD system. A good starting place is a clearance 2x the layer height you are going to print at, but you should make a few smaller test prints at different clearances to see if the 2x layer height rule holds for your particular situation and orientation. Have fun and happy printing!

"Failsafe" ESPHome Fireplace Controller

0 0 Intermediate
When asked what smart switch to use to control their gas fireplace, you see a lot of replies "do you want to be one software bug away from your fireplace turning on?" Granted, modern gas fireplaces have safeties in place to prevent un-lit open valves, runaway heating, etc., but some people would still rather have a hardware switch standing between them and fire. This project aims to be the best of both worlds: by running 5v power to the low-voltage switch box holding my fireplace wall switch (in my case, this involved pulling 5-conductor thermostat wire using the existing 2-conductor wire), you can power an ESP board running ESPHome. By running the actual thermostat switch signal through both a DPST and a (ESPHome-controlled) 3v relay, we can be sure that the fireplace is only "active" if the manual switch is turned on.
