New angled joints from openbuilds So openbuilds have announced new angled tee nuts to allow for weird angles out of extrusion such as 60, 120 135 degrees. And to top it all off, it only costs £8 for a pack of 10. What do people think of them? Will they be the new joint of choice for Deltas? I can only see they may be a bit weak, and no means to attach 2040 v slot to the middle section. Also, I'm not sure I'd like the idea of supporting the towers from a thin strip of metal, but perhaps when paired up with supporting plastic brackets it will give an affordable means to make super rigid deltas.

How would you connect the vertical towers to a delta-triangle?
The hinges seem to have only 1 DOF. The robotdigg extruded alu-corners are much better for that purpose ( and cheap ). And they come with Nema17 brackets too.

They have build examples of delta structures, the tower would attach to the central point of the bracket. I would agree that robotdigg corners are better for the job, but they cost about £70 with the cheapest delivery option. These cost a mere £8 for 10. 2 packets of these would be more than enough to build a delta, and then brackets would have to be printed. A lot of people are still printing corners for delta, this may help to make those builds stronger.]]> Origamib Delta Machines Fri, 04 Nov 2016 06:08:21 -0400 https://reprap.org/forum/read.php?178,719495,719614#msg-719614 Re: New angled joints from openbuilds https://reprap.org/forum/read.php?178,719495,719614#msg-719614 The hinges seem to have only 1 DOF.
