NEJE Master 2 Magnetic laser changer and height adjustment

thingiverse

This adaptor allows you to move up and down to adjust the height of the laser, quickly swap the laser itself and add air assistant to your machine. This is the list of parts I've used in conjunction to the printed parts: 2x M3 counter sunk 10mm 3x M3 nuts 3x M3 washers 2X M3 mushroom head 5mm 6X 6x3mm round magnets 1x 100x25mm adhesive1mm thick ferrite tape strip 1x M3 mushroom head 10mm super glue 1x 6mm OD 5mm ID metal tube of approx 80-100mm long (any metal should work, I've used a stainless steel straw) 1x 1mm hole nozzle (optional, I've uploaded a 3D printable ) Double side tape (optional) Rubber tub and your pump air pump of choice (any aquarium or pond pipe with a minimal flow of 250lt should do fine) The super glue is to ensure the magnets don't come out of the holes, I've added also a little in the hole holding the nut for the air assistant locking bolt. The metal pipe need to be bent at an angle to project the air to the laser focusing point. I've bent the pipe by hand and then tap it with a hammer to partially restore its roundness. I've used a basic brass 3D printer nozzle that I filed down to fit tight inside the tube (i add a little Teflon tape to ensure a tight fit). I've used the metal nozzle for extra safety being the closest part to the laser hot-spot, but the 3D printed option works fine. Aside from the above, the rest of the installation is considerably straight forward, the parts prints nicely without support and snap together without need of cleaning. I printed all in PETG for extra resistance.
