Standard size Coral Mounting Plugs

The small plug is 20mm in diameter, 20mm tall, 5mm thick on the attaching disk, and 10mm diameter shaft. The shaft can of course be trimmed off if you are mounting to live rock.

Large plug shaft is the same shaft size as the small, the disk is slightly thicker to add weight

The other plug model has a 5mm hole for gluing corals discreetly. Best for sps and some lps corals like BirdsNest, Blastos, Hammers, etc

Do not use the discrete plug with soft corals like Zoas, Palys, Cloves, etc. Please use the normal one

Print weight is 3g. Regular ceramic plugs are 5g. I am working on a way to make the plugs weight nearly the same.

PRINT AT 100% INFILL OR THEY WILL FLOAT!!

I would suggest using PLA filament for the plugs as it does not degrade in the water.

No supports needed even the discrete mounting plug.

Speed doesn't matter.

I am working on a larger plug so that will be out later.
