Cerberups, a Delta-type 3D printer. It is a slight modification to a US design, the Cerberus. The modification were mainly necessary to adapt from imperial to metric, but also because other choices were made in type of materials (ie. wood instead of PLA). The Cerberus itself is based on the Rostock, of course: the first delta 3D printer.

And it's only when you need a 60 degree angle, you find that none of the tools have any setting for it, or they are so coarse/imprecise as to be completely useless... Examples: I wanted to buy a mitre box with a 60 degree cut-- unobtainable. And our mitre saw has a 30 degree angle, but manages nothing over 45 degrees... Oh well.

Second day.jpg Decided to go with wood instead of printing in PLA, for a host of reasons; Our other printer is in a state of constant testing, rebuilding, breaking and fixing and not deemed production ready yet. Secondly these printed a parts are so massive I'd need to babysit our printer for 48 hours or more. And third, adaptation from imperial to metric proves hard to do, since my extrusions also have a slightly different profile, so it needs a lot more than just scaling up by 105%, sadly.

Third day.jpg After retrieving my router and making the mounts for the three steppers, I could now bolt it in place in a more permanent fashion. Not too happy with the extrusions not being 100,0% parallel, but we're getting there. Robustness though, is already very good now.
