The original printer I was going to use to print the parts is broken, five years of part printing has taken it’s toll. I’m trying to use the parts that was able to print in the last breaths of “ye olde printer” and mixing them with parts made of wood.
Here you can see the printed socket for the nuts inside the structural profile rails.
Finished the test for the bed levelling system, copying from the best it only needs three adjustement screws to stay flat. This version is a bit smaller than needed but will keep testing with it and make it bigger when everything fits and works.
Bottom plate: 3,5 mm drill hole threaded to 4 mm all the way.
Top plate: 3,5 mm drill from the bottom plate for perfect alignement, 4,5 mm hole to allow the screw to free rotate and a 8,5 mm sunken head hole to allow the bolt head to stay flush with the surface.
Still going strong, already installed the Z axis threaded rods. After weighing the bridge (by hand) decided to switch to M8 rods to stay on the safe side. The nuts are square nuts scavenged from an old project fixed provisionally with screws.
