Turn your tavern's basement into a wine cellar with some accessories. I printed these in PLA at .1mm.
These work well with the 28mm Bar Back too http://www.thingiverse.com/thing:1477280
All files are designed to print flat and without supports or rafts. All files have been run through NetFabb.
Edit: I have added a Wine Rack Shelf insert with the bottles already in it. I have not test printed it...and my feeling is it will be challenging to print. And it will almost certainly need supports.
