As mentioned in the previous log I've designed a cable bushing to prevent the cables from taking damage due to vibration over the lifetime of the printer.

I've printed the mainframe in PLA and the three individual bushing with TPU (middle-soft)

Printing the TPU-parts:

Some parameters:

240°C (1st Layer 250°C), 30mm/s (1st Layer 15mm/s), 0.2mm layer height

Final assembly of the cable-bushings

It's not perfect (I could have switched the + and - of the 12V OUT so that there is no twist but I've noticed that to late in the process. But afterall I'm quite satisfied with this style of cable-bushing with the TPU-innerpart for better cable protection.
