Modular paint rack for Vallejo

I redesigned this paint rack for myself from scratch but most inspired design was this: https://www.thingiverse.com/thing:2549451
and one of a remix:

I changed the height of the rack and both bottle orientation available. Both cases the label of the bottle is readable (current thumbnail picture is from V1 where it wasn't ready).
I also adjusted the joints between elements, there is a 0.2mm offset which is fit for my printer accuracy, they snap togehter and in this case assembly is easier.
I prepared 3 bottle and 4 bottle in a row version.
Currently just 17ml bottle can be managed but I pland to extend it for bigget bottle also.
Parts are lightweighted to use the minimum filament.
For assembly see thumnnails but I think it's obvious.
To keep the distanse for side supports, a spacer also designed but this is optional (orange parts on thumbnails).
