The #repair of this day is the water cooling circuit of the laser-tube in #CCCAC which broke last weekend.

The fix was made with a 3D printed part (modeled in #FreeCAD) that fits over the broken barb.
Unfortunately the FDM print was not watertight even with 100% infill. So I had to put even more epoxy around the part. Not it does not look as nice, but It seems to work.
No drops after 30min of runtime.

@cccpresser aw, would've been nice to do some testing with higher temps for better layer adhesion, but that design would've probably had to have less overhangs for that

@noiob You can print a stupid 'pressure vessel' for further tests.
We have plenty of fittings left we can use for experimenting with water pressure.

I would really like to know if one can get the FDM print watertight. Perhaps bricklayer-mode?

@cccpresser @noiob you can print in abs and use acetone smoothing, works without infill.

@nd @cccpresser no, I can't print ABS
