Modules overview

Hat Systems

Hat Systems is a general purpose storage system for workshop storage of tools and inventory.

Designed with these basic principles in mind; modular, low-cost, heavy-duty/durable and spacious. The module sizes is designed to fit onto EUR-palett, with a footprint size of 120x80 centimeter. This allows them to be moved around easily in an production or workshop environment, or even transported between locations.

Originally developed as for use in-house at Fellesverkstedet, now also in use at Bitraf, and open for reproduction across the world.

Contributors

Conceptualized for Fellesverkstedet by Hans Christian Skovholt and Graham A. Hayward.

Modules have been produced by Jonas Sætervik, Siemen Cuypupeiers and Anthony Poldervaart. And by Thomas Winther at Bitraf.

Have you made a Hat Systems module? Or have designed additional modules? Let us know!.

Example configurations

Storage shelves

Per palett: 2x2 Rack, with 3x Drawer Regular in most of the racks.

Laser material storage

1x Material Storage with 1x Bridge on top.

Roller table with drawers

1x Rack with 3x Drawer Regular, a benchplate on top and wheels mounted underneath. Very useful for moving large cutsheets and finished parts around workshop, to and from CNC router.

Collaboration table

2x Rack with a tabletop made out of one old sacrificial layer from CNC and one white-painted sheet (120x240cm). Comfortable to stand and work around, or one can sit on bar-style stools.

Machine tools workbench

The machines on top of the work surface are each attached to a plate with chamfered edges. An opposing chamfered edge in back, and hinged profile in front locks the plates in place. This allows some flexibility in moving the machines around.

Prerequisites for making

You will need accesss to a large-scale CNC mill/router, capable of handling cutsheets of at least 60x80 cm (120x80 for current bridge design), and cutting 18 mm OSB. Examples include the Shopbot PRS, or an extended Shapeoko/XCarve.

If you don't have access to such a machine, check out your local FabLab, makerspace or hackerspace! Or find someone to manufacture it for you locally using Fabhub.io directory.

Ready-to-use cutsheet geometry is included, but you will need to set up the toolpaths yourself using the CAM software for your machine.

Modules

Sketchup project source, for modifying or creating new modules.

Rack

The base module, which drawers fit into.

Rack assembly drawing

Made of 18mm OSB.

Is put together with 8 countersunk socket head M8 x 50mm bolts and square nuts M8 x 13 x 5MM (DIN 7991/ISO 10462). The countersunk bolts facilitates placing two units side by side on a pallett.

The rack is assembled with bolts in order to make it possible to dissasemble for transport. But could theoretically be glued or screwed together as well.

Drawer Regular

Regular drawer that will fit most stuff.

Made of 12mm OSB, as well as 6mm MDF for drawer bottoms.

You will also need one drawer bottom.

Drawer BigOne

Supersized drawer, takes the place of two regular drawers in height. Otherwise identical to Drawer Regular.

You will also need one drawer bottom, see above!

Bridge

Forms a solid surface on top of two racks, as well as housing for two regular drawers. Useful to create a working sturface, with height comfortable for standing work.

Material Storage

Full-width module for storing materials vertically.

Work-in-progress! Files should be scrutinized before any attempt to produce.

Trash cans

Work-in-progress! Files currently missing.

Trash can rack, including 3x trash cans.

Trash cans module

The ER20 collet and milling bit holder on top is also to-be-released.

TODO

  • Add picture of Bitraf island module, and design files
  • Material Storage: Finish/verify files, mark complete.
  • Rack: Remove mostly-unused bolt holes in sides. They stay still by their own weight.
  • Add a template .SVG file for drawer label (for ease of making on laser/printer)
  • Trash cans: Publish files, create assembly drawing
  • Milling bit holder: Publish in separate project, link here
