CR-10 Frame brace bracket

thingiverse

Human: Not big or smart, just an angle bracket that lets rods or bars support the 'goalpost' gantry. They have a V on the back that fits snugly into the groove in the rails so they're firmly secured. Both holes are 5mm and you can just remove the end covers and slide a 5mm bolt into place, then tighten it up - no need to modify the bolt. Bars can be anything (I used some old pergola frame) drilled at 6mm to give a bit of play, so you don't have to tension the gantry; just lock it where it is and tighten the end bolts. I might change to something more elegant than the pergola bits - maybe aluminum bar with drilled ends?
