Texas Instruments LM35DT/NOPB is a wonderful and a cost effective temperature sensor however it is hard to mount it on anything that is not a PCB or a heatsink without it being a bit janky.
I designed these little brackets to allow better and cleaner flexibility range than duck tape.
One version has 10mm flanges for larger zip ties with optional M4 holes and one with 5mm flanges with M3.
The only catch is that the TO-220 tab hole needs to have tapped M4 threads which some might find it bit iffy since the threads might strip easily due to the thin size and soft metal like copper or aluminium. Nonetheless, I tested it and it is stronger than one might think, I have a not stripped the threads even after tightening it. Definitely consult with datasheets if you want to avoid electrical shorts for any other devices than the LM35.
3D printed using the exact attached .gcode with Creality Ender 3 S1 Pro in ESUN Matte Black PLA+ at Super 0.12mm quality (15 to 19 minute print time).
I recommend printing at 101% scale for a better fit if you want to make your own slice.
I hope other people will find these useful. I can happily provide .step files on request.
Bits that I used for my assembly:
- M4 Threading Tap (with WD-40 for tapping lubrication)
- M4 x 8mm Screw (Yahata Neji Cross Truss but any other non-countersink screws will do)
- M4 Spring Washer
- M4 Plain Nut (the main spacer)
