This is two small pieces, that fits around the sensor leads on the Optic Spy, hold in place by a piece of heat shrink tubing to support the sensor and hopefully protect it from accidentally breaking when put in the toolbox along with the rest of your electronics tools.
Notes:
These are pretty small, takes only 10-15 min to print, but you might want to slow down the printer to let the layers cool off a bit, before continuing with the next layer. I printed these with the tip down.
