uTracer Enclosure

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
