Fish-fry holding pen.

A 3D printed fish tank lid holder measures about 180mm cubed. You can watch this video to see how it works: https://www.youtube.com/watch?v=3fG2xTjECCU. This design incorporates tulle fabric into the print, requiring a way to pause your printer while securing the netting in place. The "A" files print two parts at once, spaced 2mm apart. This creates a great lid-hinge and makes it easier to align the parts for gluing. Keep in mind that both sides of the holder will be joined the same way but need to be separated so they can fit together properly. "B" files are designed for smaller printers and print one side at a time, 180mm square. You may choose not to add a lid if you already have one on your fish tank. Printing tips: By default, all parts are 2mm thick (high). 1. Pause your printer at 1mm to secure the tulle mesh over the print using small clips or a 3D pen on the edge of the bed.
