POINTY.CAM is a wearable thermal camera for chefs. This ring lets you see everything in your crosshairs as a pixelated heat map. Noah Feehan designed the hardware and tapped me to design an enclosure. Bonus: it is open source!

- 1x 1.25in (32mm) strip of 1/8" neoprene tape (McMaster Carr part #93375K25)
- 2x M3 thread forming screws (McMaster Carr part #96817A908)
- 1x printed top
- 1x printed bottom
- double sided tape
These instructions cover what it takes to get a working version of the POINTY.CAM board assembly into the enclosure. Please check POINTY.CAM for updates and instructions regarding the electronics.
To ensure the electronic components don't rattle around during use, employ a few strips of double stick tape to sandwich the battery between the GridEye board and the screen. You can also use little strips of neoprene tape to pad the space separating boards to shore up the fit between the electronics and the enclosure.
Start by printing out the top and bottom of the enclosure. Stick the strip of neoprene tape to the inside of the "ring_top_02.STL" print. Place the board assembly into the bottom half of the enclosure, lower the top half over it, and secure with two M3 thread forming screws.
When the enclosure is sealed up, you can still access the power switch through the cutout next to the screen. It's sized to fit a pen, paperclip, or DSi stylus - use whatever's handy.
This was printed with a 0.6mm nozzle and a 1.2mm wall thickness. The top half of the case has a large flat area that should make for easy printing without a skirt, but the bottom half will really rely on your bed adhesion. Go with a raft if you have trouble getting the first layer to stick properly.
The top half of the cover (ring_top_02.stl) has a sharp overhang throughout the first few MM of printing. I would advise using a slower extrusion speed or support material if your printer is hit-and-miss with overhangs.
