UNO mod case bottom.stl
Remixed from "Slim Arduino Uno Case" by Torsten August 21, 2012, available on thingiverse. I editied it in tinker cad, so not the greatest work. The lid doesn't close firmly so i used a bit of velcro over the top. I used tactile switches with a stem height of 13mm, these pop through the holes with a MM or two to press. Be sure to mount these before the LED's so you can use them to judge the height of the LEDs.
I also found that the supports affect the text appearance, maybe best print text side up.
I used screw terminals rather than barrel jacks for the lights so you may need to edit the side entry if you use barrel jacks.
Maybe check the mounting eye, my viewer looks good, but it didn't print very firmly.
It's a bit of a mess, but its a headstart for someone.
