K40 Laser Beam Combiner/Alignment Remix

thingiverse

I really liked the idea of this beam combiner setup but wasn't too keen on the idea of having to glue parts together to make it work. I changed up the beam combiner so that it uses M3 screws and has pockets for M3 nuts in the body. No need for the extra plate or glue anymore. The round baseplate works fine by itself, but again, I didn't want to glue anything so I added a couple of recesses for some 3/8"x1/16" neodymium magnets so it just snaps in place. Everything else is the same (other than not needing the one faceplate to glue the nuts in place.) There's a seller on Ebay that sells the combiner lens for under $40, I'm just waiting on mine to get here from the slow boat. Print the base flat with supports touching the bed, and the body can be printed without supports just fine.
