       I have written down all that I know about designing functional mechanical parts for 3d-printing.  Took two years, but I finally managed to finish it... Please let me know what you think!https://blog.rahix.de/design-for-3d-printing/#3dprinting @3dprinting #dfm #DesignForManufacturing

       @rahix @3dprinting Wow this is great work!For R2.2 about horizontal holes, I accidentally discovered another option. Model horizontal holes as threaded holes even if you do not intend to use the threads to mate with another part. The serpentine path of the threads allows very large successful overhangs.The downside is, of course, that it's computationally expensive to model, and it's easiest when there is a standard thread form with a minor diameter compatible with your design intent.

       @rahix @3dprinting Here's another one: The solution is one that's also often used for additional security of metal joints as well: Use additional screw locking measures, like lock-nuts or a threadlocking adhesive.A small (2–3 thread) untapped portion with a design size of the major diameter (thanks to internal circle shrink) or slightly smaller will work like a nylon locking nut. This can with with only partially tapped threads in post processing, modeled and printed threads, or threaded inserts.(Crush rib threads usually provide this locking on their own, as far as I can tell.)
