rough surfaces 90% gone. only have to find good coating for long lasting finishing paint. i'm thinking 2K clear coat on that water based paint.

FWIW...
DaJMasta:
I'm working on some variants of the same, had thought since encountering the first breaks on these parts that 3d printing would be a great way to work around it, and then you uploaded some really good models to start with - these plastic bits have been so prone to failure, especially in shipping, and seem to be nearly impossible to otherwise source.  I've got a "remix" posted on thingiverse of both the foot and the bumper for it with some slightly modifications - got an in-progress version of the bezel as well, but I've had a couple of issues with my enclosure preventing me from getting a really good print out of it for proper testing.


In any case, what kind of materials are you using?  The soldering iron to join it is an interesting take, but if you're using ABS something like acetone welding or plastic glue may look a bit cleaner (though, it does look quite clean painted).  I assume the rubber bumpers on the feet are printed in some kind of elastomer?  I've been using TPU and while it strings enough to need some post-processing, it's done a good job of mimicking hard rubber.

Hello Mechatrommer,
How did you glue the pieces together? I mean - did you use a solvent like dichloroethane, or some kind of special glue (from what material are the printed parts here)?

It would also be useful to print these parts so that it was possible to manufacture the input adapter on your own.
