After seeing how multitudes of boats are stored at marinas, I was inspired to build a version for our beloved Benchys. This rack will hold up to 16 standard Benchys.  
 

The print does not require any supports as long as your printer can reliably bridge. Just don‘t change the orientation (front of the rack on the build plate). Because there are so many small parts, there may be a fair amount of stringing but it cleans up pretty easily. 
 

I printed mine in Prusament Galaxy Silver PLA and it turned out great.
