Just a simple design for a desktop clock:)

This was designed for a WPPL (HQ3268) clock. Not Sure how common this model is, It's just the one that I happened to have on hand. It was a tight fit, you may need to drill the hole out a little.

You need to print 2 pieces, the ClockStand and the BackCover. I printed mine with zero top layers in prusa slicer to get the gyroid infill aesthetic. With my infill at 22.5%, I can't see the top layers of the cavity at all. You'll also need the clock, the hands, and some weights if you'd like.

1.) Take the hands off the clock carefully, unless you're gonna make your own anyways
2.) Press fit the clock through the back of the ClockStand. Push it as far as you can, making sure that the hour hand fitting pokes through enough. Mine just barely poked through but it still worked. If you need to take your clock out, it didn't damage my clock to just push the mechanism back through the hole (with a gentle hammer).
3.) Add a bit of hot glue around the inside of the clock. Be sure to avoid the mechanism or the battery spot. While the glue gun is out, secure some weights in the slot under the main cavity. This will help keep the clock steady, as well as help you orient which way is up.
4.) Set the correct clock time and add a battery. After that, you can snap in the BackCover. I added just the smallest amount of hot glue to hold the BackCover on. It should still pry off just fine when I need to change the battery.

Enjoy!
