Mostly Printed CNC Laser Mount

Update: October 15th, 2016 - After switching to the HicWic universal tool mount on my MPCNC, I've built an adapter to connect my laser mount directly to the system. If you're using this design with the HicWic mount, you won't need a conduit clamp. For setup information, check out the Vicious1 website's laser guide at vicious1.com/the-2-8-watt-100-laser/. I'd like to thank Vicious and HicWic again for their contributions! The laser mount you see here is featured in my $100 2.8 watt laser write-up on the Vicious1 website. I wanted something that could be installed or removed quickly without having to remove my spindle, so I designed this adapter. The connector used is a 4-pin XLR chassis mount, which can be found on eBay. The shroud has a channel for accepting a piece of laser shield plexi like what Jtech Photonics sells, or you can get tin snips and create your own laser shield from cheap laser goggles. To ensure secure and quick height adjustment for the shroud, I glued pieces of 1/4-20 thread rod to both the shroud and the mount. The threads mesh together for a tight hold. There are also circular cavities in the shroud for holding neodymium magnets securely once the threads mesh. The tapered dovetail on the mount fits snugly into the conduit clamp, but there are magnet cavities there too if you need extra hold. To avoid slippage, I recommend wrapping electrical tape around the conduit before putting the clamp on. You'll also need a 6-32 screw and lock nut for the clamp. A 55mm laser focus "gage" is available as well.
