Honeycomb shelf support bracket

I needed somewhere to store my filament, so i designed these. 

Easily holds over 10kg (with 22x1800mm long shelf). The slots are 201x23mm.

The sides can use the many different designs for the honeycomb storage wall system.

These where printed out of PETG. I recommend  at least 4 walls and 20% infill (gyroid).

Step files included if you want to modify.

Update 2024-04-19:

Had a request for a bigger version of these so I added with 250.2x18.5mm slot as well as with 220.2x18.5mm slot (These are untested as far as weight capability and printability)

The shelf is my original with added honeycomb wall insets.
