Laser cut Tile replacement case

thingiverse

Human: Glowforge ready to print. I've got a stash of Tiles with dead batteries, so I ordered some replacements from Digi-Key. The Tile's construction is pretty dodgy - soldered battery, ultrasonically welded, it's like they're trying to make it impossible to replace the battery without destroying the case. Digi Key part number CR-2032/VCN P660-ND I was thinking of 3D printing one, but I've got a laser just sitting there, and some proof-grade materials calling my name. Why not use them? From 3mm Acrylic cut out the middle disk that houses the electronics. From 1MM Maple veneer (with 3M adhesive backing) cut: 1 top. The red dot is where you press the veneer to activate the tile. The small dot in the keyhole is positioned over the switch inside the case to trigger the button when the cover is pressed. I used the adhesive on the veneer to hold it in place, but Kapton tape was my second choice. 1 bottom. This is the large round disk with three speaker holes. 1 "Shim” layer The same profile as the 3MM acrylic. 2 Board shims They fit inside the compartment to hold the board and speaker.
