Great repo with lots of great information. I think it would also be helpful if you added some info about kerf values for different vendors when laser cutting acrylic. When I ordered my sandwich case I found a huge variance between different vendors for the kerf values based on the thickness and the material. In the end to keep things uniform I ended up selecting 1.5mm acrylic for all my layers and used multiple layers for bottom and top. Thanks
e.g. ponoko says their kerf is 0.15mm for 1.5mm acrylic, but pololu uses a kerf of 0.1778mm for the same material. Big blue saw said they set the kerf to 0 because their technician would adjust the laser to reduce the waste to 0.
