HMMH - Hour Meter, Magnetic Heater

thingiverse

Enclosed are models with and without the hour meter. I recommend using an hour meter unless your printer already tracks hours. Wire it to the fan that is only on when the LCD is on. PLA may be too soft when warm, so print with PETG or ABS, or try printing in resin. Designed for EPAX, Phrozen Transform, and original Photon printers, but also works on other metal-enclosed printers such as the Shuffle. For plastic printers like the Photon-S or Zortrax Inkspire, simply stand it up in the corner. There's also a Moai version with magnets only on the bottom - useful for any printer with a steel base. This model doesn't need support to print if you print it face-up. Heater (100-watt recommended but you can use 150 watts and just don't use both black wires): https://www.ebay.com/itm/12-24V-PTC-Cars-Fan-Air-Heater-Constant-Temperature-Heating-Element-Heaters/172773930677 https://www.amazon.com/gp/product/B07F3PBX7J Hour meter: https://www.ebay.com/itm/HM008A-LCD-Hour-Meter-DC4-5-to-60V-Voltage-waterproof-Automobile-hour-meter/202266617316 https://www.amazon.com/gp/product/B01E3AETM2 Temp controller: https://www.ebay.com/itm/Microcomputer-Thermostat-switch-Temperature-Controller-DC-12V-Digital-LED/163270307427 https://www.amazon.com/gp/product/B07K7KJ788/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1 https://www.ebay.com/itm/12V-Digital-LED-Microcomputer-Thermostat-Controller-Switch-Temperature-Sensor-R/163356256545 Magnets must be 1/4 inch or 6mm diameter and at least 2mm, 3mm, or 1/8 inch thick.
