Ender 3 60x60 fan mount with ABL probe

thingiverse

Supported probe diameter is 12mm using the adapter and 18 mm. I created this because my hotend cooler failed giving me a 60mm fan lying around. I tested it on the Ender 3, it should work for Ender 2 & CR10. I minimized air flow from the hotend cooler to the printed object. ### Screws For the 60mm fan I used two m4x16 screws. Apart from that I used stock screws. All holes are a bit smaller than their corresponding screws so they should work. ### Fan Voltage If your printer provides a higher voltage than the fans maximum you need to use a resistance or a "step down dc-dc voltage converter" available on ebay aliexpress asf. ### ABL Probe I am using the 12mm diameter inductive sensor LJ12A3-4-Z/BX and a 1mm "pertinax" printing surface on top of the metal bed. Keep in mind that the inductive sensor detects metal within a short range so the paper must not be larger than 1mm. The 18mm diameter LJ18A3-8-Z/BX might provide a larger detection range. A nice test on ABL probes: https://www.youtube.com/watch?v=il9bNWn66BY Here is a nice HowTo on the pertinax printing surface https://threedom.de/pertinax-als-3d-druck-untergrund-dauerdruckplatte.
