Welcome to my page :^)

I am a new member of the comakingspace and new to most tools in the shop.

My current projects are learning to use Autodesk Fusion and the laser cutter.

When I have my materials and introduction to the machine, I already have a bunch of laser cutter projects on my todo list. I want to start small with a bunch of board game knick-knacks, drawer organisers, desk doodads and stationery accessories. Down the line I want to learn about 3D printing and create some basic ATLAS compatible drawer housings.

Always keen to collaborate in block printing projects :D

Currently I am working on a guide on how-to design collapsible designs using slot and tab joints.
