Z leadnut Bracket for Solyslva CNC

thingiverse

Replacement Z Bracket for Solsylva CNC. My Z axis was acting up, so I decided to upgrade from the hardware store all thread. These days you can buy a cheap leadscrew from Amazon that comes with flanges, couplings, and pillow bearings for less than what I paid for just the coupling when I built the machine. So, I decided to replace the all thread with a T8 300mm leadscrew. The original bracket is screwed vertically into the wood between the Z rails, but unfortunately, trying to remove it pulled it right out. It's screwed into wood, which doesn't work well if you try to redo it. I also figured that because all the force is vertical, it made more sense to attach it to this wood horizontally, as vertically all the forces were on the threads in the wood, which was already bad. It's a drop-in replacement, assuming you have a similarly sized leadscrew flange to the one I bought. If you want to use the horizontal screws (there are recesses for M3 nuts, so use M3 screws), you'll need to drill two holes through the wood bracket between the Z rails. The hole is there if your original bolt is in place (the vertical one that attached the original bracket); you'll also need to drill holes to attach the Z flange, which don't print as it seems the mounting holes vary. Pics are attached of my print and on the machine.
