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:
- Fold the OctaSide part into an octagon
- Click it in place around the OctaBottom part
- Push the opposite side into the OctaTop part
- 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.
- 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.
