This is a magnetic probe holder for a single probe. The hole is big enough to fit regular pH, ORP or other probes along with the thick Neptune Apex temperature probes. The magnets are pre-coated resin neodymium N50 high strength magnets capable of holding on less than 1/2" glass (1/2" will probably work).

  • Holds a single probe, easy to install in tight places.
  • Printed out of black PETG.
  • Can fit the thick Neptune Apex temperature probe.
Check my other listings for 3D printed reefing equipment. I will accept reasonable offers for multiple things bought from me.

Please note that these are 3D printed parts. That means that the surface finish quality of the part will not be directly comparable to an injection molded part. Although not very common, there might be small surface finish defects, or rough spots. The goal is to have a fully functional, as described part. This disadvantage to 3D printing is reflected on my pricing as well. Polished surface finishes, is definitely something that can be achieved to a certain degree with 3D printed parts, but it's a time consuming process, something that definitely cannot be offered for the price range my products go for.
