Sony SM3 Case for freestyle libre

thingiverse

Small case used to fix Sony Smartwatch 3 above freestyle libre glucose sensor (for use as cgm). If you don´t know what this does you probably don´t need it ;-) The Case is small and fits 4 neodym-magnets with a diameter of 5mm and heigth of 3-5mm. They are a tight fit, I used a pair of pliers to push them in. DO NOT USE HEAT to make them go in, it will kill the magnetism! (yes, I know now). The watch sits in the case quite nice, but needs to be fixed with some tape. Take care not to put the tape over the the charger-hole ;-) On the arm I use "fixomull" Tape from the pharmacy and 5mm Diameter Neodym-Magnets with a heigth of 1mm. I put the tape with the nonsticking site on the watch and press an old freestyle into the hole. That way the tape is being pulled in the right position. I then peel of small parts of tapecover above the magnets on the watchcase and let the 1mm magnets for the arm snap onto the sticky part of the tape. That way all is in the right position.... Strength of this design: small, easy to attach and remove, cheap.
