I then started testing with the acrylic once I was happy with the overall shape. I created prototypes to help me test and learn which methods are best. 

Learned

• Overheating the acrylic causes bubbles to form, leaving that texture within the form 
• Using a nonsmooth surface to curve the acrylic leaves extra dents and bumps 
• After heating and bend the acrylic, the tab would not fit in the slot because the form changed
• Acrylic glue leaves a mark after it dries so I used Gorilla Glue instead 
• Bending using a spoon produced inconsistent results and caused strange curves in the sides of the form (see rightmost image below)
• The best way to create the form I wanted was to bend it by hand into just a simple half-moon shape that was consistent throughout the entire form.
