The individual parts of the organizer are connected using connectors at the bottom. For better connections, it is possible to use polygons connectors for high parts. No need glue.

No need the supports. For speed print i use draft.

UPDATE 7/12/2021 Added new holder

A new holder is added. This is a holder for paper clips. I used a cylindrical magnet measuring 10x8 mm, which is inserted in the middle at the top. In G-Code, straight couplings are added.
