Handy Darkroom Developing Tray Clip

This little clip has a multitude of uses in my darkroom. 

• I use it to keep prints from spilling out of the tray if I'm using a tray with running water to wash prints. 
• I use it to keep my thermometer from falling in the liquid or falling out into the sink
• I use it to keep a hose/tubing aimed into the tray
• I use it to prop up trays when drying

Print it on its side (the way it appears in the model file) so that the layer lines run the long direction.  This ensures it's strong enough to clip on the side of your tray and won't break when you flex it.   You'll need supports.

I print mine in PETG. PLA doesn't give a long-lasting spring.
