So, a while ago I posted about a grounded (inverted) delta project of mine, promising stupidly optimistic completion dates and seemingly giving up on the project. For those of you unaware, it is a redesign of the original GUS Simpson reprap with some basic improvements and some design changes.

Fear not! I didn't give up, only procrastinated (and life got in the way). The project is nearing completion, I'm just finishing off the shoulder, which took a surprisingly long time to get the geometry right to accommodate the new stringing and figuring out how to arrange everything on the base of the printer. After that, I just need to knock together an effector which shouldn't take more than half an hour (famous last words). In this finalizing stage, I'd like to ask if anyone is interested in building one and helping me debug and improve the design in the coming year? Any features you want to see?

If interest builds around the printer I'll put together assembly guides and FAQs. I'll also be posting some STLs of the parts that are ready, and eventually the OpenSCAD code once all the parts are modeled (and the clutter is cleaned up.... yeeesh....). There are 3 parts of this printer that aren't off the shelf/3d printable and will need to be machined (frame, oddly shaped print bed and an optional removable print surface). I'll be putting together a CNC in the coming months to machine these for myself and would be happy to machine a set for someone else. Worst comes to worst, the frame could be 3d printed and the bed either replaced by an off the shelf shape (no automatic steps/mm calibration ).

So far, it looks cool if I do say so myself.

EDIT: Also, suggestions for the name are very welcome. So far I've gone through several names. Spyder, because the way it prints reminds me of how a spider spins a web and spelling it correctly would be boring. DeltaGear, because its a delta driven with gears. Geared Up Delta, as a nod to the GUS (Geared Up Simpson).
