Here's a shape for a Homemade Tix clock.

On my first print for the whole Tix clock (picture in blue) the wall was too thin. So i made a new version with bigger wall but i have not reprint it.

I recommand enough wall so that every square are opaque.

I recommand to print in black. Because otherwise light can pass through the wall.

If you want to make it completely here's a link to my github project (Warning: In french)
