Makerfarm i3v X, Y & Z Limit Switch Covers

thingiverse

8/7/2018 Update Updated the X-axis limit switch to clear the M8 Lead screw Nut mount. I covered the solder connections to the X-axis limit switch, using an idea I had previously used on the MPCNC build and modified it for the i3v. I also made covers for Y & Z axis while at it. For the Z-axis cover, ensure 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'm using a titan extruder now and my X-carriage is narrower. For the original carriage or wider carriage, you might lose 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 to get a better idea of what height to locate the Z-axis limit switch cover bracket. I inserted a small allen wrench into the V-Slot to keep the t-nut from falling out as shown in the 4th photo. After installing each part, I double-checked the wires to make sure the solder joints weren't touching any other metal and the wires didn't get caught under the M5 screw head. There's an openscad source and STL for each of the 3 axis covers. The X-axis also has a mirrored copy if you're using the limit switch on the opposite side. There are two STL files used for reference in the X-axis cover openscad file to show how the x-carriage hits the X-axis limit switch.
