Laser bed center NEJE 1.5" round

thingiverse

I really enjoy my little NEJE DK-8-KZ 1000mW laser engraver but it can be frustrating to get things perfectly positioned where you want them. By the way, these engravers are an absolute blast for $80 off on Ebay. This is designed to help center a 1.5" wood round that fits snugly around the bed and should allow you to get as close to perfect center as possible. It installs without any hardware or rubber bands. I noticed that what my laser thinks is the actual center point is not exactly centered in the bed (it's off by .5mm). However, I deliberately placed this one directly in the middle. The other issue I encountered was that the wood rounds are not always exactly 1.5 inches in diameter. To accommodate larger ones, I had to do a bit of sanding, and for smaller ones, I stuffed a piece of cardboard into the gap to get them to fit.
