Probe and Dosing Tube Holder

[RoanokeReef]

Morning, my google skills are apparently lacking today. Looking for a place that sells Probe and Dosing Tub holders that I can silicone/glue into my sump for a permanent solution. See plenty of hang on and magnets. Thanks for the help!

Check Ebay. They have a lot of options. I would avoid anything 3d printed.
