This is a magnetic optic water level switch holder. It will hold the most common optic switches on the market. 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).

  • Printed out of PLA.
  • High quality strong N50 pre-coated neodymium magnets.
  • Designed for optical switches with thread diameters of 15mm (if you have a bigger one leave me a comment with the order).
If no color is specified during checkout on the notes, black ones will be shipped.
Optic level switches not included, just pictured for reference.

Check my other listings for 3D printed reefing equipment. I will accept reasonable offers for multiple things bought from me.

Clear PLA, i.e. PLA with no color pigmentation added which makes it translucent, is also available. Leave a note with your order that you want "Clear" as color if desired.
Note: I offer these in black PETG as well. If you would like that option, please contact me. There will be a 25% increase in price for this material.

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.

Material Selection: Some arguments have been made about pigmentation in PLA filament and it's effects in water in case of leeching. You can order “Clear (transluscent)” parts which is PLA free of any pigments. Just leave a note in your order that you want "Clear" parts. I have personally used black PLA in my tank for many years with nothing but success. You can also ask for PETG if you are concerned about durability of the PLA part. Just contact me.

If you have a color preference please make sure to put it on the "note to seller" field during checkout. If you do not do that, I will use the default black color and I may not be able to honor any request you have after your payment is complete.
