Bulkhead compression fitting

I needed fittings to pass wiring through the bulkhead on my printer controller case. I came up with these 5mm and 7mm fittings. I printed mine at high resolution (0.15mm) on a Malyan M200 using Solutec PLA at 205C on a 60C heated bed (build surface is BuildTak).

The parameterized model is available on Fusion 360. https://a360.co/2WTTH6q
