@BigJasoni as always a wealth of knowledge! For me, when I see a TK i think Star Wars and its really unfortunate, no designers have capitalized on this. With so many persons having access to 3D printers now, a well designed set of files is gold. You are so right about thickness and flexibility of 3D printed parts etc. I am so happy you are started your designing but I know how hectic things get IRL. I'll keep an eye out just in case you ever finish them. As for me, I am about 90% completed printing the CG trader files but as you said, time to get the Dremel out, lol. Once I'm comfortable, I'll start a build thread an hopefully you can give me some pointers also. Thanks again!
