For years I avoided 3d-printing because of various reasons ...
- material (plastic only)
- time (takes for ages)
- limited size (can't go bigger than 20 cm, still the bigger the longer it takes)
... but, there are objects that can not be done with a CNC machine, at least not a machine you could afford. So, price dropping, quality increasing, reduced fuzz about tweaking the printer, I made the step and bought an entry-level printer. As with my CNC machine I was looking to make something useful right away, so I started to design adapter for the spiral hose that is used for dust extraction.
The first one took two trials, with the second I succeeded right away. I treated the surface with sandpaper and a coat with lacquer for cosmetic reasons only.
Actually I am pretty happy how this worked out.
