So I got mine up and running finally. Some problems I bumped into (some had been mentioned in this thread before): - The teflon tube I bought at a local hardware store was not the right one. Being my first 3D printer I didn't know how the tube should be. This one looked right, but it was not rigid enough and maybe a bit too flexible and with more friction. All this caused the filament to jam thby FraNtik - Delta Machines

You can see how I setup mine in my gallery For the LCD I used M3 screws, but some of the holes in the case and display are 2 or 2.5mm, I had to make them a bit wider. The fan I had made it difficult to pass the LCD cables, so I used wire ties instead of screws, that left some room to pass the cables. My J-Head mount had some overhang inside (where the hotend fits), I had to heat and drill someby FraNtik - Delta Machines

Yeah, I'll try some twisting, but I won't pass the cables again (pain in the asby FraNtik - Delta Machines

Column length is 480mm. Ah, there you go, mine are 500mm. there is the 20mm difference, and maybe I set my endstops bit too close while calibrating and ended up with that 217mm mark.by FraNtik - Delta Machines
Almost done with mine. Here are some pics of the process The hobbed bolt is a bit larger and I had to add extra washers to prevent the extruder from bumping into the carriage. I passed extra cables thru the columns to place a female USB in the base (it has some erratic behavior, probably from interference from the motor's cables) and a power connector. The MAX Z I get is 217mm with 3mm cristaby FraNtik - Delta Machines
Good list. You are missing the RUMBA board there. And the bowden connectors and tube. Most of the screws and nuts can be found in a decent hardware store. For the build platform I saw this post in Delta google group: Borosilicate glass . It leads to here. For the Europeans with no way to cut the aluminium and steel rods themselves: I used Motedis. They cut it to the size needed, and also sellby FraNtik - Delta Machines
Here is something I'd learn the hard way. Not all Traxxas joints are the same. I ordered 12 joints froma local hobby shop. Traxxas ref. #2742 They look the right shape and size. But they are not, the rod hole is 2mm, the screw holes M3 and the hexagon shape is 6mm in width (it won't fit in 3DR's rod adapters) I went ahead and make the holes in the joints and platform wider so I could use M3by FraNtik - Delta Machines
Awesome design, thanks Richrap. I have most of the BOM ordered now. One thing that worries me: When I ordered the printable parts, I left off the list the LCD covers. I was planning on printing them myself once the 3DR is up and running. But now I realize those parts won't fit in 3DR's bed (I swear I saw the bed as 180mm, but now it says 170mm) Is that so? Shouldn't the printer be able to repliby FraNtik - Delta Machines
