Remix of i3v Lead Screw Nut Plate

thingiverse

I have been pondering upgrading my 10" i3v with an M8 lead screw for a while and liked the idea of not having to change my Z-Motor mounts. I decided to take cperiod's idea: https://www.thingiverse.com/thing:2917730 and modify it slightly, making it more rounded. I also increased the diameter from 33.0mm to 34.4mm. This resulted in a loss of approximately 7mm in the X build space compared to the original M5 rods. If you want to change the diameter to 33.0 or smaller, simply adjust the variable **Mnt_OD** in the openscad file. If I need more X distance, that is what I will do. It should be easy to modify this plate later by loosening the M8xM5 coupler and removing the screws from the plastic nut plate, pulling out the M8 lead screws, replacing them, and then reassembling. While changing this part, I printed newer versions of the X-motor plate (https://www.thingiverse.com/thing:853811), X-idler plate (https://www.thingiverse.com/thing:878023), and X-axis limit switch Holder (https://www.thingiverse.com/thing:1959535). I also created a plastic M8xM5 coupler for the z-motors, which can grip 19mm of each shaft. I have not noticed any difference in prints, but it does feel more solid now. I printed all the parts using esun PLA+ with the gyroid infill of the Slic3r Prusa edition at .2mm layer height and 30% gyroid infill for the i3v_lead_screw_nut_mount_Mod_Rev18.stl, .2mm layer height and 20% gyroid infill for the X-Axis_LimitSwitchHolder_Rev12.stl, .2mm layer height and 50% gyroid infill for both the i3v_X-MotorMount_rev32.stl and the i3v_X-IdlerMount_3Wheel_rev14.stl. There are openscad files available for this nut plate and coupler if you want to adjust any of the variables. The files are commented fairly well, making it easy to understand how to modify them.
