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.

A 10,000 nm CO₂ laser tube? Looks good.

@pinkmoon I have not yet tested it it actually lazzzers after the repair. Let's hope it does.

Using silicone on glass would also be a solution, similar to how aquariums are sealed with silicone.
