Automatic shelf generator!

Over the new year break I expanded the functionality of the Housifier boxmaker to create boxes with an open top. Once that was done, I tried to work out how to add internal partitions to make shelving. That’s solved now too, and I have (digitally) assembled the first output of the system… I think it’s ready to print. The editor will be available shortly. Stay tuned!

Usage: Move the mouse around in the flash window to rotate around the model as it assembles.  Get Adobe Flash player

  1. Any thoughts on how strong it will be without adhesives? How much tolerance is there on kerf? You’re going to get Ponoko to make one right? Given their maximum thickness of material, what is the maximum size you could make?

  2. The kerf (the amount of material that the laser cuts away) varies between materials and at different thicknesses. The typical thickness for the materials you’d be using here is 3mm, which translates to about 0.1 of kerf. The system can compensate for different kerfs and offset the path accordingly, so it should be able to be press-fit without any glue for all materials.

    I’m definitely going to get one made! Their maximum laser-cut material is 790mm x 384mm, so the largest shelf you could cut would require each piece to be less than those dimensions. They also do CNC router-cut designs where the thickest material you can get is 19mm and the part sizes go up to 1219mm x 1219mm – with that you’d be able to start making full-sized furniture, but the kerf is a full 6.7mm, so you need to put together some extra compensation techniques to get the parts to fit together, particularly with the corners in concavities.
