Cuvette holder (LOVIBOND laboratory equipment)

On our laboratory we use a LOVIBOND infrared device to measure the color of our products, The new plastic cuvettes didn't fit wel in the original holder. With this new holder it fits very well. We use three different cuvette sizes, this holder can be used for all of them.

Two different designs, use the one you like the best ;-)

I have added the Fusion360-files also.
