Adjustable 40mm Fan BL Touch Mount

thingiverse

I wanted to reclaim space on my X-Axis, so I figured a 40mm BL Touch fan mount was needed. However, after a few iterations of a static mount, I felt it pertinent to redesign it from the ground up so there was at least some level (no pun intended) of Z-Axis adjustment. I printed with ASA, but you can use PLA. The design was created in a way to reduce supports needed, though YMMV. Printing: 1. Spacer isn't necessary, but I'd recommend printing it at the same time a. due to the proximity of the BL touch, it can slightly increase hot end fan noise b. use of spacer reduces/eliminates this noise 2. Parts have sides with curves and flat sides. Print flat sides down. BOM: 1x M3 nut 1x M3 nylon lock nut 2x 5mm socket cap screws 1x 15 to 20mm socket cap screw for carriage adjustment 4x 15mm socket cap screws for mounting through frame and fan Assembly: 1. Press M3 nut into carriage. Bottom of the nut retainer hole is formed to shape of nut (i.e. pointy side down. :D ) 2. Insert M3 nylon lock nut into receptacle in frame. It will be loose, so don't flip the frame without covering it. 3. Using needle nose pliers (tips on either side of the nut), lock the nut in place while you thread the screw through. Ensure the screw is pushed all the way through the frame until you feel a tiny bit of firmness. 4. Mount the BL Touch to the carriage with the 5mm screws. The screws will tap the plastic. 5a. If you printed carriage and frames separately, gently flex the sides of the frame to allow placement of carriage. Make sure to not the sides -> One side has curves, the other has chamfers. Match the carriage to the frame. 6. Begin to thread the adjustment screw into the carriage nut 7. If opting to use the spacer, sandwich the part between the frame and fan with curved sides toward fan. WARNING: There is a limited range of adjustment, so do NOT force the screw. The adjustment should take little to no force, so if you feel a decent amount of pressure, use a shorter adjuster screw. By printing and using this mount, you are doing so your own risk... Just don't channel your inner Hulk. :)
