Description

This is a calendar that you can reuse over and over again. Each month, just pop out the tiles and set them in place for the new month. You should mount this in a frame or something with an incline, as nothing but gravity keeps the tiles from coming out while it's in use.

Looking at that, what would happen if the numbers were embossed permanently but the day signs could be moved?

Instructions

The original design was done in Inkscape, and I exported to PDF for import into Corel Draw for the laser cutter as that keeps the dimensions better than CD's SVG import.

To get the updated version, I cut a back from the same piece of acrylic to match the size of the front piece, then used acrylic cement to adhere the two parts together. I then used a Sharpie to fill in the etched day-of-week letters, then fine sandpaper to remove the sharpie on the top surface and give the whole acrylic a frosted look.
