VW Polo 2016 Dash Vent TM1637 Mount

thingiverse

I did a digital temperature gauge for my step-son's Polo as his car, and most other modern cars) doesn't have one. It makes use of a TM1637 LED display unit. This is then dimmed at night using a 10K LDR as light sensor. We made an adapter pipe into which a DS18B20 is mounted. This pipe goes into the top radiator hose where the water temperature going into the radiator, before being cooled, can be checked. NOTE: You have to split the model into separate objects as there is a 0.10mm gap between the face and the housing. The TM1637 screws into the housing with 2mm screws and the face plate is a friction fit over it.
