lens cover customizable

thingiverse

This is a completely customizable lens cap. I created this item for my projector just a few days ago. After seeing https://www.thingiverse.com/thing:3899398 , I decided to upload my cap too. The unique design is that if you forget to remove the lens, when you turn on the projector, you see a message on the wall reminding you to put the lens cap back in place. You can easily modify the diameter by changing only the variable dL; to change the text, simply edit it in the middle of the code.
