Laser Cut Wooden Perpetual Calendar 2026 with Acrylic Gears

You need an idea for a nice product? You are not to creative? Either way: Try using AImake to generate a first picture of something you want to build. I was amazed of the design of the calendar AImake generated and so i tried to build this calendar on my own and design it with the help of a CAD software (sketchup) as you can see in the second picture.

From my CAD i then exported the dxf-files. I also generated some frame with gears to use as background of the calendar with AImake (see the prompt in the picture)

After that i used the “Gear Template Generator” to create the moving gears with 1:3 and 1:4 ratio (together 1:12) for the transmission of the days (12 times a year) to the calendar weeks (one rotation per year). In XTool Studio i then finalised the gears and added the numbers and months and also traced the frame picture to be able to cut out the background.
 

With the settings in the XCS-Files i then cut the acrylic (3mm), the walnut plywood (3mm), the birch plywood (3mm) and also the 3mm wooden round stick into 22mm pieces.
If you need more of the small acrylic rings, just copy them, they are used to hold the gears in place on the wooden shafts. The moving “month” part has to be assembled according to the pictures: You will need another 12 wooden sticks (length: 7mm). After this assemble the other shafts and gears according to the pictures above, add a rubberband and a stick on the bottom to secure it and to be able to wind up the month gear.
Hold everything in place and attach the final acrylic front cover to hold everything in place.
Have fun with the build!

Here is a short (sorry for the bad quality) video of the running calendar:

By the way: Don't glue the year to the calendar but rather glue those three parts together to make it interchangable!
