So I to the end of a road and the end of the road sign would not take my normal goto for these https://www.thingiverse.com/thing:1904542
So i whipped out my trusty calipers and went home to mull my options. And this is what i came up with. The 2x4x10 block is for supergluing to the bottom of the drawer to retain the drawer from blowing away if wind goes rushing down one of those channels. Right now, unless you have very small fingers I don't think you'll be able to grab the built in grabber. I am not sure what i can do to make that easier to grab, if you have an idea message me.
Otherwise, Cache on!
