"Frabjous" is a scupture originally created by Georg Hart. It's made of 30 identical S-shaped pieces.

My version is a bit different. It's designed to be cut from wood and has self-interlocking pieces. No glue required!

More photos at my blog post:


The design was made to be cut from 4mm plywood. You can also use a bit thinner material, 1/8 inch plywood should be fine as well

  • cut 30 pieces using a laser cutter
  • assemble (see links above for assembly hints)
  • connect the pieces loosly first until you have all 30 pieces in place. otherwise you'll have problems putting the last few pieces into their correct place

Hey where can I find the assembly details since the link cannot be found.

Some hints are described here:
Apart from that, just look at the photos. Sorry, nothing better available...

What software did you use to make this?

Hi drayde,
I used your files and have cut a frabjous for myself: http://vbp.maxnet.ru/laser2/#frabjoushttp://vbp.maxnet.ru/laser2/#f...
Matchbox is supposed to show the scale. I used 6 mm plywood

What is the scale on this thing supposed to be for the side of the tenons? I'm cutting 3.175 (1/8") birch and each piece is ~15cm long.

I cut it out of 4mm plywood, but a material a bit thinner should work just fine too without having to change the size.

whats the easiest way to modify a svg to a dxf? I have a cnc and really want to give this a go.

Inkscape can load svg and export dxf.

I like what George Hart and also Bathsheba.

Mathematics + informaique = laser sculpture


Suuper :)

I made this for my dad for his birthday. Here's the file I used to cut this, each of the 30 pieces are arranged to fit on a 24x12 inch board.
