Re: 3DR "Simple" Delta Printer
My MendelMax 2.0 is having a child! I've printed out a set of test parts for the bottom of the printer and assembled them to see how it's going to work out: Everything fits well. The Misumi 20x20...

Hey GPSNEW, I am currently building the 3DR, just finishing up the electronics and I printed all the parts on my RoBo3D Printer. The quality is awesome. I would love to do the parts for you. Maybe...

Here is something I'd learn the hard way. Not all Traxxas joints are the same. I ordered 12 joints to a local hobby shop. Traxxas ref. #2742 They look the right shape and size. But they are not, the...

I didn't really like the KCmodels links (some were ok but most had too much slack) so I went for Traxxas #5347 instead.. 3mm Ball bore and M4 inside the shaft. I did not use the 3DR rod adapters but...

Sorry for the beginner question, but is it feasable for me to build me one of these as my very first 3d Printer? (once you've released the design) i absolutely adore the design, also it's propably...

@Vladimir_Lukashuk: For me it is a non-issue. With well placed strings all but the most extreme prints will be trapped. In that extremely rare situation you can cut the string and remove the part....

PVC tubes looks good, they probably need to be glued in order to hold them. Even scrap 2X4's would work

QuoteJohnSL Yes, all the parts are designed to be printed on a Printrbot Simple, which has a 100mm x 100mm bed. I don't know the maximum height off the top of my head, but it's less than 90mm. lol FYI...

Could the steppers be face-down where the PVC is, with a gear to the rods? The orientation of the steppers in this design and the open space between them could let you run (slowly) all three rods with...

You should put the steppers on top... This will decouple them from the frame movements. Just my 2 cents. PS: The PVC tube idea is sweet

You could build strut supports surrounded by a half-circle guide that a PVC size 'fits' into, so you could either string easily or slide a piece of pipe in place, or not use it at all?
