Large Kossel M8 Threaded Rod Braces for 1515 OpenBeam (like Kossel XL kit from builda3dprinter.eu)

thingiverse

I purchased a large Kossel kit with long 1515 openbeam extrusions. Unfortunately it's not very rigid. These braces use M8 threaded rod to massively increase rigidity. The STLs provided work for beam length 360mm wide and 750mm high. If your beams are different lengths, download the scad file and adjust the parameters. You will get new STLs and also the console will output how long you should cut your M8 threaded rod (for 750x360 that's 804mm). Bill Of Materials (for bracing all 3 sides): M8 threaded rod (length dependent on beam length) qty 6 M8 Nut qty 12 M3*8mm machine screw qty 24 M3 nut qty 24 M3 wash qty 24 To use this, you need the kossel2020 repo:https://github.com/Jaydmdigital/Kossel_2020 And the nutsandbolts library:https://github.com/JohK/nutsnbolts
