Quick tool change for Creality CR-10 / Ender series

IMPORTANT NOTICE: Since Thingiverse was having performance issues and people are reporting getting 404 errors, I decided to place all my designs on my own website https://properprinting.pro/product-category/3d-print-files/ All files can be downloaded from there for free and all updates and new designs are placed on there too.

I decided to upgrade my Creality CR-10 printer and came across this cool laser head which can easily be added to this printer. There are four small neodymium magnets on the laser head that allow it to be attached to the metal extruder shroud. I wasn't convinced that this is stable enough so I designed a generic tool holder.

This turned out to be much cooler than I expected because I am not only able to place the laser cutter, I can also add a grinder and suddenly I have a tabletop CNC milling machine! You can even change between hot ends so you don't have to unscrew the nozzle if you have multiple hot ends and extra cables/connectors. It is also easier to clean or replace the nozzle because you can hold it in your hand.

The position remains stable if you replace the tool. I tested this with an indicator (DTI) so no need to level your bed after replacing the tool. However, I recommend to add an adjustable Z-stop. I am personally quite fond of this one https://www.thingiverse.com/thing:2757323. This makes nozzle changes much easier.

I have created a YouTube video in which I explain how I came up with this idea and how it is mounted to the 3D printer. Enjoy! https://youtu.be/oK3877cbBeM
