Dishwasher slider sign (Dirty/Clean/Custom)

This indicator slider is used on the dual dishwasher system at our makerspace. We have one machine with clean dishes, cups and cutlery, and the other one for dirty.
This means our users take items out from the clean one and returns them to the dirty one. 
When the dirty one is full, its started and both sliders are flipped over, and the process restarts.

The slider has two integrated 10x3mm magnets in the slider and one in between the signs that it locks onto.

Our sliders has the text signs printed with the lowest part in black and the top 4 layers in white/brown.

There is an included Fusion-file for custom text.
