Durable Octagonal Net Cup

The net cups I previously use always broke after a while because of poor adhesion when printed standing up.

This cup prints in 3 parts flat on the print bed for superior strength. It also includes a lid to close off the top to not let light down into the nutrient below.

To assemble:

1. Fold the OctaSide part into an octagon
2. Click it in place around the OctaBottom part
3. Push the opposite side into the OctaTop part
4. Add some CA Glue in the trough where you connected OctaSide to OctaTop, I find it easier to add it after connecting the pieces but works to add it before as well.
5. Wait for the glue to dry and you have the strongest printable net cup!

Print settings:

These are designed to be printed with a 0.4mm nozzle at 0.2mm layer height in a stiff material like PLA och PETG. The OctaLid optional part is best to print in a flexible material if you want to add it around the plant after the fact.

Customizability:

The ready .3mf-file is made after my needs of a 55mm outer diameter and a 50mm height with a 2mm rim. You should be able to scale it in the slicer to get other dimensions, just remember to stand OctaSide up so the scaling matches the final assembly.
I have also included a .step-file for more customization and also a .f3d-file if you want to change the parameters in Fusion 360. The parameters hole, height, thickness, rim and lidHole all works and should update the model fine.
