Automatic bed leveling Optocoupler CR-10, Ender 2, Ender 3

thingiverse

I was asked to modify the design to add slots at the ends, which makes perfect sense. I've now included this modification in the file. This is a custom case I designed specifically for the Optocoupler on my CR-10s and Ender 2 printers. I used the ebay parts listed below and drew from a wealth of information available online to create this design. It's comparable to the EZABL kit, which is truly amazing. However, one of the thrills of this hobby is making things myself - or with the help of friends. This case fits perfectly on CR-10 models and I used it for my Ender 2 as well, using only two fixing posts instead of four. I was planning to create another case for the Ender, but this one worked so well that I didn't bother. The lid is designed with a friction fit, eliminating the need for screws or other fasteners.
