Here's one way to trick out your CR-10 enclosure: add as magnetic tool strip so that all of your tools are right where you need them. This required drilling an extra hole, but it wasn't too hard. Now my work surface is clean and ready for other projects.
When drilling acrylic, be very careful to use masking tape on the area first on both the inside and outside. When you drill use very little pressure to gradually remove the plastic. If you do not follow these instructions the plastic is liable to chip or crack the enclosure. Its not hard to do, but if you simply force the bit into the plastic with no tape it will crack and chip.
