expandable modular holder

Modular constructor that forms holes about 15-16mm in size. Can be combined in two layers and serve as a support for tools, pencils. It came in handy for me as a support for decorative bamboos (rubber bands damaged plants, and ropes rotted, with this thing, my plants feel better :-D ).

As models, I suggest you:
- module 1/6 circle (~11mm x 10mm. hole in the center: ~2mm with a variable profile.)
- a connecting spike that connects the modules of the circles (~7.40mm x ~3.25mm x ~2.70mm).

The assembled circle forms a hole with a diameter of ~16.60mm and a shell with a diameter of ~37.18mm

When assembled, it looks like a part of a spaceship :-D

I printed with the following settings:
- Material: PLA
- Heater temperature: 200 -> 193
- Table temperature: 53 -> 40
- Adhesion: Brim (You can experiment with printing without adhesion settings, I previously printed these details without Brim...)
- Experiments: Enable Bridge Settings, Bridge Has Multiple Layers
- Infill: 20% (P
