It was surprisingly simple, since I find poster tape works fine to attach the glass to the tabs on the Kossel - no new parts needed. I just had to crimp the thermistor and bed heater wires, attach the heater (it's adhesive-backed), and enable the heater by defining a thermistor type in Marlin.by brandonh - Delta Machines
There's a huge installed base of Kossel builders - in fact, I'm aware of 7 (including 2 derivatives) within the local RepRap group. Yes, you'll have more calibration to do, but it's not that hard, and the upside is a extremely fast, lightweight printer. Having built both a Legacy Kossel with strings, like the 3DR, and 2 Kossel Minis with belts, I have to say that belts are the easier option andby brandonh - Delta Machines
FWIW, I ordered this heater last week and it came in a few days. It works great on my Kossel Air and immediately fixed my curling problems for Simpson parts. It was super easy to install; just had to crimp 4 wires and add housings, apply the sticker-style heater to the boro glass, and enable the thermistor in Marlin. However, a regular-size Kossel Mini may require a few cable extensions. Mby brandonh - Delta Machines
Quoteowens Quotenicholas.seward @pjoyce42: You can print it in the orientation given. Most printers can bridge that far. It may sag but you have tons of layers until you get to the gear part so most printers will self-correct. However, there is an untested version here. I am not sure if the tuner can be inserted. I think it can. No issues at all putting the tuner in; there's plenty of clearby brandonh - Delta Machines
Quotenicholas.seward @brandonh: Added the branch. Great idea. I am new to source management. I will merge it once we can verify that it doesn't cause any problems. Thanks! Looks good here. Let me know if you have any Git/GitHub questions. I'm sure you'll be seeing Simpson pull requests shortly.

I just ordered all the parts, but one more question, then I'm done for awhile. About the Bowden connection - interesting to not see a pushfit here. I take it the m4 nut must be threaded onto the PTFE tube, which is then secured with the bowden nut. Did you use RichRap's method to externally thread the PTFE tube? Never done this, so wondering if there's an easier way; it seems slippery. Did yby brandonh - Delta Machines
Quotebrandonh Nicholas, that mod looks great. Why not make that the default? I don't see any disadvantages. If there's a part you're on the fence about, you can alway push it to a branch on GitHub. Then everyone can have access. Also related to the part, where does the string go from the tuner spool? This is what I'll call the part that the string goes in and then turns, on the guitar peg wby brandonh - Delta Machines

Thanks for the info, Nick! Got the latest Inventor downloaded and the assembly looks great. I used to do all my designs and Inventor and teach it to FIRST groups back in '02 and '03, and after spending time with OpenSCAD lately I'm tempted to go back to Inventor for the more complex stuff. Questions here plus more questions inline: - Is there a place with a bunch of pictures of assembled Siby brandonh - Delta Machines
This is awesome. I will make one, in bright red. I ran Slic3r on the parts using Charles Steinkuhler's Wally .ini in the github repo, and the total came out to 1.07 Kg of plastic. I can't see the assembly files until I upgrade my Inventor version (a 4GB dl), but in the meantime, a few questions for Nicholas: - What slicer did you use for the parts? What settings do you recommend? - There's aby brandonh - Delta Machines
