Filament spool rack/shelf (honeycomb, NO AMS)

Tried to find a model which would equally work as a shelf or a rack (until I decide where to hang it at least). Found one…but holes appeared to be wrong size :(

I made my own version. One for 1", and one for 20mm wooden dowel. Clearance of 0.2mm (0.01") added so that dowels can get in. If any other version needed - let me know, I have Fusion360 sources, so changing would be fast

It requires no AMS for multicolor version, but I'd also put single-piece version which has no multi-color

Multi-color one requires simply to print both parts separately and slide one inside another (it has a tight fit, so want fall off later)

NOTE: 

• hanging on a wall better to do upside down (middle dowel on top), this way it's easier to take spools out and also bigger spools wold fit without touching the wall
• keeping as a rack best to do with middle dowel on bottom, then angle of spools is better

UPD: Thanks to @Slawterr who shared and let me post the modification to the bracket that will permit the use of #6-10 screws found in hollow wall anchor kits.
