Kossel Cross Brace Brackets

Information

Kossel Cross Brace Brackets

You will need to print 3 sets of these braces. Each brace has a relief channel in the back to take a wire (from an end-stop, for example).Use these in conjunction with turnbuckles and spectra / kevlar / steel line to help stop the frame of your Kossel from twisting.I have got these fitted to the machine, but the Kevlar line that I was using was too thin and snapped. I will try again with spectra line.There is a bit of flex in the brackets when printed at 60% infil, but it has to be an improvement on the original setup.

Technical

- 6 Printed brace brackets - 12 M3x30 bolts - 6 M3x20 bolts - 12 M3x8 bolts - 30 M3 plain nuts - 6 turnbuckles or other tensioning devices - Spectra / Dyneema line (or other non-streching line)

<p>Looks like you have 20x20 extrusion and you are still seeing flex? I noticed after going to some super strong(N52) magnetic linkages that I have considerably more friction in my setup that results in my OpenBeam 15x15 extrusion having visible torsional flex.</p><p>I think my next delta is going to have 20x60 extrusion with Igus T linear rails for ultimate rigidity :) </p>
