Permanent Laser Mount Ender 3 Pro

UDATE 4-14-21 I moved the bltouch mount up 2.2mm due to being to close to the print bed. UPDATE: I completely redesigned the bracket. It's much smaller and now incorporates a mount for the BLtouch. I left the original bracket if anyone still wants it. The redesign is v5 in the files. This was an effort to eliminate tooling changes between printing and etching on the Ender 3 Pro. This setup creates a screw on mount in place of the provided magnets for attachment. Once completed, this allows you to switch from laser to extruder by simply flipping a couple of switches. Make sure to only have the switch on for the task you are performing. You will need: 4x M3x20 screws 2x M3x16 screws 4x M3 nuts 2x M3 T-nuts 12 ft 26awg wire 3x JST-XH male connector 2x JST-XH female connector Laser from Creality store (or any laser that matches the hole pattern) This switch from amazon: https://www.amazon.com/gp/product/B08LYZ4P5H/ref=ppx_yo_dt_b_asin_image_o02_s00?ie=UTF8&psc=1 I did not include the wiring setup. Its pretty straightforward. The existing switch leads wire up to the JST-XH male connector and attaches directly to the board where the filament fan connects. The female JST-XH connectors wire up to each switch. Connect the laser and filament fan to each female connector. If there is a demand for a more detailed explanation I will add it in. Note that the original bracket is not set up to be compatible with the BL touch if you are using their provided bracket. I could not get mine to work at the time so opted for the manual dial indicator bracket found here: https://www.thingiverse.com/thing:4737853. My original bracket was designed to fit with the dial indicator bracket.
