About this 3D model

I wanted to create something useful to enter into the calendar design contest. With this in mind, I thought about people at work, and what they typically have on their desks. Besides calendars, almost every office has family pictures! I created this light box calendar to accept any 75mm x 75mm litho or light box image, and I designed it in such a way that they can be easily changed out. I left a hole in the back to run wires for your favorite light source and even included a storage compartment to hold the extra days, months, and years. The calendar items are attached with 5mm x 2mm magnets. I did use a drop of glue in each hole to make sure they didn't come out. Be careful when you're gluing in the magnets, so you get the polarity right and the items stick properly to the box. Plate 1 is the days, months, and years. I did a color change at layer 16. Plate 2 is the main body and the lid. I did use supports for the main body to make sure the bridge across the top of the litho hole looked good. I designed the lid to fit very tight. If it's too tight for you, try scaling the lid up by a percent or two. Plate 3 is an example litho. It's a deer in a field with a barn and tractor. It's 75mm x 75mm x 3mm. Ignore the horrible quality of the one in the photo. The first one I created I made too thin and it left holes when it printed. It's been fixed in the example file provided.
