I have around 240 Vallejo 17ml bottles, I was planning to get a rack but the original rack and some other brands take too much space for 240 bottles, and my space was only 105 cm wide.

So I decided to design my own rack, it looks crowded but I am able to put my bottles in the space I wanted. Any brand with 25mm round bottles should fit on this rack.

The straight model holds 54 bottles and it is in one piece printable, it should fit on most printers, the height might be a problem for some printers, printing height is 234mm.

Supports are not needed for the straight version, just print on it's back, same way as uploaded STL file.

If you print more racks, there is a printable joiner to attach the racks together, you can also use 5mm bolts to connect the racks together, see pictures.
Print every second rack mirrored to get better looking longer rack

I don't need a corner but decided to make one for those who need one, to create a 90 degree corner you have to print two of these 45 degree versions, each holds 28 bottles, normally I do not upload anything without printing and testing before, but since I don't need a corner on my work-space, I did not print one.

Make sure to check the images I uploaded for tips, also be aware that this print needs around 450gr filament, I had to cut down a lot to get 2 racks from 1kg filament spool, but I also wanted print without supports, the 45 degree one needs some support, the straight version does not need supports as mentioned above.
