Square rotating wall clock

This is a clock where, instead of having linear hands, the entire clock face rotates. This produces interesting geometrical patterns throughout the day as the two hands intersect at various angles.

*You will need to print a face, a frame, an hour hand, and a minute hand.*

_It is intended to be more difficult than a typical clock to read, as a sort of statement on the modern obsession with precise time. The hour and minute hands are identical, other than the hole for the shaft._

STLs are provided that fit a movement I own. There is also a .scad for customization to whatever movement you find.

The various surfaces are rounded so that the edges are less likely to catch on one another, but it still happens, usually when the hands are 90 degrees apart. I recommend finding a fairly rigid filament. Ensure that everything is stable and parallel. There should be small gaps between the face, the hour hand, and the minute hand.

Design tips:

* The hands ought to fit tightly onto the movement (you may need to press a bit). If they don't fit tightly, you'll need to adjust some parameters and try again. I just use calipers to measure and then add maybe 0.05 mm.
* The shaft hole in the face should be slightly larger than the movement's screw.
* The face should be just thin enough that you can screw the movement's retaining nut on for a few turns.

Printing tips:

* The infill on the face will be visible (as you can see in the photo). This can add to the…
