Initially i wanted to laser cut the plastic as the polypropylene was 2mm thick. However i had no assess to a laser cutter that was large enough to cut out the template. So i then had to measure and cut the plastic by hand.
With help i used steel rods and clamps to ensure the plastic didn’t move so that i got a clean cut. I also tested glues to see if they were transparent and strong enough to hold the plastic lid together.
For ease i varied a little form my original flat design and chose not to cut two thing slices up the slides of the lid instead i cut a basic square.
