Whiteboard corner and siderail

thingiverse

Had a poster in a gallery frame, didn't want the poster anymore, and really needed a whiteboard, so I figured I'd repurpose the acrylic, the poster (turned backwards), and the cardboard backing. My 1st plan involved the holes in the corners, but I forgot what that plan was. 2nd plan was to stick it to the back of a door, but the sticky squares failed. Ended up just screwing the bloody thing to a wood wall using 3 corners and one rail in the bottom right, figuring that configuration should make it somewhat easier to take the acrylic out if I need to wash it or something. IIRC, the legs of the corner triangles are 118mm, as is the rail. Channels in the pieces are 5mm deep and 5mm wide. At that width, I had to crush the cardboard a bit to get everything to fit in the channel, but I was tired of this project at that point and just made do.
