3D Printed Frag Racks and Magnets

ksir17 · May 1, 2023

I'm currently playing around with printing some frag racks for my tank. The biggest issue I'm coming across so far is what magnets to get. There are a bunch of choices out there and it seems like ceramic might be the way to go. Also trying to find some that are strong enough to hold through the glass (12 mm). Anyone have recommendations that have worked well for them in the past?

From my experience, ceramic magnets aren't very strong so you might have to go with a normal coated magnet and just check it every couple months to make sure it isn't rusting.

Yea the coated magnets will work and are strong. I use old Tunze magnets to make rocks that attatch to the back wall. This would work well for a frag rack, imo.

K & J Magnetics has pre-sealed ones, a bit pricey (you get what you pay for), but I haven't had any issues with anything I've DIYed with them.

Could you PM me a part number for the magnets you used?
