CNC routed cat tower

Andrea asked me to make a cat tower as a gift for her niece.

I might have got a bit carried away.

Version one failed user acceptance testing. This is version two.

I wanted this with no screws at all, just wood that slotted together and locked itself in place. I also wanted it to be easy and obvious to assemble correctly and impossible to assemble wrong. That part turned out ok.


Packs down for easy transport.

The cut-outs were generated using the Ready reaction-diffusion simulator and the Grey-Scott algorithm.


Ready has some weird glitches that left me scratching my head for a while but I worked out a suitable tool-path. Start with the component in Fusion 360.

Screenshot that and turn it into a bitmap mask.

Import the mask into Ready and run the simulation and tweak the parameters until it looks ok.

Take a screenshot into Gimp and simplify.

Take that image into Inkscape and trace bitmap to get paths. Save those paths as an SGV.

Insert that SVG into a sketch in Fusion 360.

Extrude to cut the component.

And then repeat for different parts with different parameters.



Andrea finished the raw ply with linseed oil to avoid anything toxic and old carpet cut out and stapled on. It was cut in cat shapes, in case anyone hasn’t worked out the theme yet.

Smoofy approves.
