NOTE: I have depreciated this model in favour of https://www.thingiverse.com/thing:2667913.
One of the drawbacks of the original design is that it hits the frame of the printer and so it is necessary to extend the X end-stop to avoid printhead collisions with the frame; a consequence of this is a reduced print area, around 0.5cm.
I reworked the design to avoid this problem as well as to make it thiner and lighter: from 13.47g to 9.52g (around 30% lighter).
In order to meet the assembling recommendations, I suggest printing out a draft design, mount it on the printhead, mount the BLTouch and then measure the distance between the base of the BLTouch (not the pin but the plastic base) and the tip of the nozzle. The base of the BLTouch should be 8.3mm (+/-0.2mm) above the tip of the nozzle. I have found that to measure the distance between the two it is better to do it with the printer display —the Z height displayed is in mm, and by looking at the difference between the two. The procedure could be: take an object, placed on the bed and move the Z-axis until the nozzle barely touches the object. Take note of the Z position. Relocate the object so it only meets the BLTouch on its plastic base (not the pin). Adjust the Z-axis until the BLTouch plastic base barely touches the object. Take note of the new Z position. Performing the corresponding subtraction of the two values gives you the distance between the tip of the nozzle and the plastic base of the BLTouch. Do the necessary maths to determine how short or long the draft BLTouch is for your printer. Contact me with the new dimension and off you go with your tailored BLTouch holder!
