This is a very strong and stable wine rack that can be made to hold as many bottles of wine you require.
Start off with a small rack and then add to it at any stage as your wine collection grows (if you don't drink it faster than you accumulate it).
 

It certainly not the most ornate wine rack on this site or Thingiverse but it was designed to be strong and modular and to hold as many bottles as I want (in my garage as the wife will not have them in the Kitchen).

Each wine rack should consist of 8 corners (on their own those would make a 2 X 2 rack to hold 4 bottles) then together with side, middle pieces, stretchers (full stretchers to any middle section and half stretchers to any side or corner pieces) as required to make the size of rack you need.
There are dovetails to fill any holes left by the radii on the sections which enhance the looks and also adds a great deal of strength.
You also will need some Vee head (or countersunk head) M4 screws of any length from 10 mm to 25 mm. No need to tap the holes just use screws as self tap and screw then into the holes directly.
There is a PDF to show how many of each part is required to make racks up to 100 bottles (10 X 10), so the one I have made which is 5 X 3 and highlighted in yellow below requires 8 corners, 6 middle sections, 16 side or edge sections, 24 dovetail_2 pieces, 16 dovetail_4 pieces, 44 vee head M4 screws and that will hold up to 15 bottles.
 

The holes for the bottles should be big enough to take most standard 750 ml bottles and certainly all the ones I have had fit.
In the unlikely event you have some bigger bottles or always get magnums then you could of course scale everything up.

All parts print without any supports except full stretchers which require support from build plate only.
