BLTouch Mount for 5015 fan

thingiverse

**!! Warning !!** Before doing any Auto Level, check that when the BLTouch is deployed (the probe pin is out), the BLTouch's pin hit the bed BEFORE the nozzle. When the BLTouch is not deployed (the probe pin is in), it should not hit the bed. Otherwise, you may damage your printer! -------- #Introduction This is a collection of BLTouch mounts to attach a BLTouch on a 5015 fan. They should be compatible with any cooling device as long as the 5015 fan screws can be used to fix the support. Because the height of the mount will depend on the cooling device and on the hot end, several mounts are provided. #Determine the height of the mount The height in the stl file name is from *the middle of the top screw of the 5015 fan to the bottom of the mount branch where the BLTouch is screwed*. To determine the mount length, put a piece of paper on your bed and bring the nozzle of your hot end down to touch the paper (just like when you are doing the bed level or adjust the Z offset). Measure the distance from the middle of the top screw of the 5015 fan to the bed (= to the nozzle). We want the mount length + the BLTouch length when not deployed = the distance you measured - 3.3 mm. So: H : distance between middle of the 5015 screw to the nozzle l : mount length l = H - 40.15 - 3.3 = H - 43.45 For example, if you measure H = 75 mm, then l = 31.55 mm. Choose the BLtouch_support_30.5mm_x.stl model #Determine the side of the mount If the mount is screwed to the back of the 5015 fan (where the sticker is), choose BLtouch_support-xx.5mm_R.stl model. If the mount is screwed to the front of the 5015 fan (where the rotary part is), choose the BLtouch_support-xx.5mm_L.stl model. #Printing the mount Support is required (10%). To avoid that the mount touches the rotary part of the fan or obstructs the air flow, there is a 5 mm space between the mount arm and the fan. That's why support is required. It should be easy to remove. #Mounting You may need a washer between the BLTouch mount and the 5015 fan.
