I needed a tool shelf for the corner of my lack table, but the existing ones I found had too many different shelves and holders I didn't need… So I decided to design a modular tool holder/shelf system where you can print and use only what you need!

I'm planning to add holders for different sizes of table legs (if needed) and more useful shelf modules! Let me know if you have any ideas!

Updates:

2/1/2023 - Added two-part main holder for round 40mm table leg and a three-block long large bin shelf module.

Print instructions:

All but the hook module can be printed without supports. Any amount of infill is fine. Save your filament and use as little as you can. I printed mine with 10% and 2 walls.

I suggest printing a tolerance test first with a holder piece and a connector to see how they fit together and how the holder fits to the table leg. The connectors should be tight. Tight enough that you might need a calibration hammer to spank them in. There's a holder shelf for the hammer too…

Assembly:

Use connector pieces to connect different modules to the holder piece or to each other. All the connector slots are the same distance away so you can assemble them in any orientation you need.

Notes:

Even if the holder is tight to the table leg, at some point it will start sliding down (especially Lack leg). I suggest putting a rubber band or something like blu tack under the holder.
