Saltwater Aquarium Frag Rack

Frag rack sections for saltwater tanks.

Fusion 360 .F3D file is also attached.

You use at least 2 Connecting Pieces to connect 2 sections of Egg Crate together.
Connecting Pieces are probably going to be friction-fit depending on the Settings you have used, but I still recommend Super-Glue.

You can use the Rod Holder - Square (basically a bushing to make a round rod fit in a square hole), with 1/2 Acrylic Rod. Again - I recommend super-glue.

The Square Bushing has a lot of clearance within the Egg Crate, it is not a friction fit. You can accidentally super-glue it quite off-level, but it also gives you more creative flexibility as a result.

Recommend 2 people to put this together with Glue, depending on your configuration.

I have also found that printing the Connector and Rod Holder with 0.1mm Layer Height gives best results. Using 0.24mm worked ok for me, on the Egg Crate itself.
