Like many 3D Printers, I have accumulated quite a few boxes of backup filament and was looking for a good storage solution. There are hundreds of models that are available already but I could not find what I was wanting. I was picturing a set of shelves that could hold the unopened boxes and also the partially used rolls that I have in vacuum bags. I always liked Tinker Toys and Toy Brick’s so I started working on some ideas in Fusion 360 for a set of parts that could be connected to create a custom set of shelves that could start out small and then be added to as needed in the future.

This modular shelf set is a collection of parts that can be printed and then connected together to create a custom arrangement. The parts can be added in any direction to expand the arrangement.

The basic set of components include 9 different parts:

There parts are:

• Crossbar with slots
• Crossbar without slots
• Post
• Backstop (connects to the slots in the Crossbar)
• Plug with a top cover
• Plug without top cover
• Block
• Foot
• Half Plate (for the shelf, two connect to form a full plate)

Theses are some pictures of these parts connected together:

This is a complete shelf combination:
