I had a lot of fun making this file. I roughly followed the design of a perpetual calendar I received a long time ago from my grandmother. I almost made the mistake of just putting 1-6 on each block and then realized I had forgotten 0, and 7, 8, 9, blah blah. All the pieces are snugly fit, had to use a hammer to lightly hammer them together, so no glue was necessary. I’m rather proud of it. I’ve made a lot of other item already but this one makes me think of grandma.
1/8" plywood (mix of bass and maple, as that was all I had left over)
Approximately 176 square inches of material
Designed on Illustrator, about 2 hours of messing around
Utilized MakerCase.com to get some of the boxes started
Last year (pre-GF) I used it as a prototype for an elective makers class with 9-11 year olds and had them design their own. Their designs included a tree with nests holding the “date eggs”, a turntable with a vinyl 45, and a flying dragon clutching small people. That last one was conceptually good but difficult to make happen.
Here is the one I made. I call it my Cthulu calendar.
