Tevo Tarantula SN04 proximity switch bracket replacement

thingiverse

I'm replacing the original bracket that attaches to the sensor for a dual extruder setup with one that provides full surface coverage and two M3 nuts inside. The second version allows the sensor to sit up to 2mm lower, which is essential since the print head is prone to warping due to heat from the hotend. If you print in PLA, it's possible but I recommend using a more temperature-resistant material for longer ABS or HIPS printing sessions because the aluminum block can heat up significantly. Custom Section My setup has been compromised by heat deformation of the Hotend, which unfortunately bent my sensor angle off-center. Wasn't that what was behind this issue? The block without cooling warps the material enough for the sensor to tip over. In response, I've made the back surface solid and anchored it from the back with two screws that can no longer move around. However, you'll need longer screws since the existing ones are too short or sink the pocket deeper. The picture shows the original part's position so we're on the same page. I've also created a second version where the sensor sits 2mm lower. The long hole in the sensor always limited it but now it has to be firmly seated with this part. I recommend printing from robust material. If you print for an extended time with ABS or HIPS, the aluminum block heats up more because the 30mm fan can't keep up.
