These two circular wall organizers are partly designed for decoration and partly to be able to hold small items on the interior platforms.
The overall diameter is 210.00 mm. Interior dimensions of the platforms from bottom to top and left to right are:
These parts are designed to be mounted with 3M Command Large Picture Hanging Strips (16 lbs): one on the left side and one on the right oriented vertically where there is a rectangular back plate.
I printed these with 0.20 mm layer height and with a high-strength (6 perimeters) variant of the Quality preset. In hindsight I think that given that this is designed for lightweight items strength probably isn't a huge consideration anyway, so a regular speed-oriented setting could likely be used without issue.
The author marked this model as their own original creation.
