Spectrophotometer Retention Device (for X-Rite Chroma4 and Chroma5 meters)

thingiverse

I work in the medical field where our monitors need regular calibration. For most of them we have to hold a spectrophotometer against the screen for 10-15 minutes each. As long as I've been doing this I've used two large elastic bands tied together and hooked onto opposing monitor corners to hold the "puck". Being a new 3D printer owner I decided to try modeling a part to do this without the hassle of using elastic bands on monitors with rounded edges. I printed out a set of legs but they were too loose, so I enlarged the smallest part of the legs (the T shapes) by .2mm smaller than the socket that receives it. I shortened the overall size of the device by about 2 inches as it was too big for practical use on our 22" monitors. I still have to print this device in its entirety, so until then I'm leaving it listed as a "Thing in progress". Other items needed: For the sliding arm you'll need one M3 hex nut (5.2mm across the flats) and an M3 thumb screw or similar easy-to-turn screw. Update: I added two printable thumbscrews since you can't buy just one cheaply, at least not anywhere. How I designed this: I sat here with a spectrophotometer and a pair of digital calipers and measured it - designed it all pretty much on the fly.
