new laser cuts and engraves

Some new cuts / engraves done by me at the Adelaide Maker Space:
Source of files: 3axis.co

Penrose tile, good explanation here

Penrose chicken, brief elaboration here

Soldering iron bit holder. I will give this to the Hackerspace group to say thank you for their help.

USA jigsaw puzzle. Looking for ways to reduce the burning around the state names and making the small state words more readable.

Cats - laser cut by wolfpaw98 on Thingiverse: https://www.thingiverse.com/thing:2259603. Quite difficult to assembly these. Need a small file to trim the joins.
