Guide to hold a 90mm (~3.5") hole saw in place while drilling ceramic tile. I put notches on the 4 sides to make registration (positioning) easier. Made it out of PLA at .27 mm and 10% fill. I used thin 2 sided tape to hold in place and a fair amount of water from a spray bottle while drilling (cutting). I put a small flange at the bottom of the hole, because my printer tends to make the first layer a little smaller. Not sure why???
