    1. Three things that bug me about printed rulers, so I designed one that fixes them
    2. Designed a snap-fit pool towel hook for 1.25" round poles. Printed in ASA to withstand the summer heat.
    3. Took a stab at designing a screwdriver holder for my toolbox. It works pretty well, I think I’m going to make a few revision, like using rectangular magnets to increase the surface area.
