da Vinci 1.0A Z-Axis Rod blocks

thingiverse

During a print, the filament in the spool overlapped and kept the spool from freely rotating. The hot end tried to move to the position it was being told to go to and the motor made a horrible banging noise. Luckily I was there to shut down my da Vinci 1.0A but not before one of the upper Z-axis rod holder/blocks broke. I printed a few that I found here on Thingiverse all which I found to be lacking so I decided to try to fashion my own blocks. After some trial and error, I think I made decent repair parts. The z-axis rods are 10mm in diameter except for the last 10mm on each end where they are 8mm in diameter. The original part uses an 8mm hole. I made these parts with a 10mm hole that goes down to an 8mm hole. I think the deeper socket adds strength and stability. I used 10.2mm for the larger hole and 8.3mm for the smaller hole and it fits snug with no play between the block and the rod. I used Prusament PLA filament so YMMV.
