A remix of the modular stackable shoe rack with a few changes from the original:

• Slightly smaller - 215mm wide, so it will fit on my Ender 3 bed
• Hole size adjustment - I had a hard time finding 15mm rods, so I resized the holes for 5/8" wooden dowels available at my local big box hardware store
• Closed ends - Added a set of models with closed ends for a cleaner look

Like the original, it's a modular, stackable shoe rack that you can customize to any combination that you like. I've attached pictures of a couple of different ways that I've built it so far.

The 5/8" dowels fit tightly enough that the two sides hold together securely. The pieces are connected vertically by the same dowels - most of the connectors I cut at 2" long, though the ones connecting the feet need to be slightly smaller (sorry I didn't measure those!).
