uTracer Enclosure

thingiverse

I'm pleased to be able share my attempt at a 3D printable enclosure for Ronald Dekker's uTracer 3+ tube curve tracer. I'm relatively new to 3D design work so it's not perfect, but it's dimensionally accurate and fits together well so definitely does the job. Additional parts I used in this build include: 2 x 10a buck converters 1 x 10k linear, 10 turn potentiometer 1 x USB - RS232 opto-isolated converter 1 x Green voltmeter / ammeter 1 x 12v, 4 pole relay The relay switches the heater output from being supplied by by the uTracer (INTERNAL) and the external 10a switchmode power supply (EXTERNAL) and also lights the corresponding LED. I wired it so that the relay is energised whern on the EXT position- as the voltmeter is also powered when the relay is energised. This ensures that I won't be confused as to which mode is powering the heater. All these were sourced from eBay. I printed mine on an Ender 3 printer (it only just fits on the print bed!) and I made the labels with a brother label printer. If your print is good enough, the de-bossed uTracer 3+ logo can be carefully filled with paint. Bear in mind that if you don't have a 3D printer you can always send the STL files away to have them printed. In my case I printed the front and rear faces, the top cover and the bottom plate in white PLA. Then the front and rear bumpers were printed in grey PLA. The front and rear faces are then glued inside the bumpers, and finally the bumpers attach to the body with 15mm M4 screws or bolts. Bear in mind that you'll need to tap an M4 thread first. I'm glad to be able to share this with other builders of Ronald's terrific uTracer board. It's a joy to build and the instructions and support are excellent. I can't recommend it enough. Enjoy!
