Updated the X-axis limit switch to clear the M8 Lead screw Nut mount
I wanted to cover the solder conections to the X-axis limit switch. I had used this idea on the MPCNC build, so I just modified it to work with the i3v. I made a cover for Y & Z axis while I was at it..
For the Z-axis cover make sure you have at least 29.5mm from the frame of the limit switch to the wooden nema17 mount. My height may be different than yours. I am using a titan extruder now & my X-carriage is narrower. For the original carriage or wider carriage you may loose a couple of mm's width with the X-axis cover.
When changing the Z-axis limit switch I homed the Z-axis before turning the printer off so I would have a better idea of what height to locate the Z-axis limit switch cover bracket. I inserted a small allen wrench in the V-Slot to keep the t-nut from falling out as shown in the 4th photo. After I installed each part, I double checked the wires to make sure the solder joints were not touching any other metal & the wires did not get caught under the M5 screw head.
There is an openscad source & STL for each of the 3 axis covers. The X-axis also has a mirrored copy if you are using the limit switch on the opposite side. There are also 2 STL files that used for reference in the X-axis cover openscad file to show how the x-carriage hits the X-axis limit switch.
