Ornate Rotating Hourglass Wall-Mount and Case

I've had a bare hourglass sitting in my storage for a couple of years and I really wanted to put it somewhere. So, I decided to design a nice wall mount for it, so that I could display it in my small space, without being scared of it breaking.

This design uses a rotating base built on top of Emmett's parametric gear-bearing, and mounts to the wall at the center. It also has magnets that hold it upright while the sand is at the top, and some extra ornamental elements inspired by antique floral metalwork.

The model will only work as-is for a bare hourglass similarly sized to mine (about 160mm tall, and ~65 mm wide), so I've also included my design .blend file in case you'd like to remix it.

Non-printed parts:

• 1 bare hourglass (about 160 mm tall, and 65 mm wide)
• 10 m3x16 screws (though you might be able to get away with shorter ones)
• 8 6x2mm cylinder magnets (optional, but they help keep it upright when the sand is on top)
• 2 to 4 wall screws
• glue (whatever you like best, but I used epoxy)

Printed parts:

• 1 rotating base
• 2 end-caps (plus 2 spacers if your hourglass doesn't fit)
• 2 side arms (Pick one depending on whether or not you added spacers)
• 4 magnet arms
• 1 wall spacer

Instructions

Print the base and end-caps first, and test the fit of your hourglass. If your hourglass is slightly too big, print the end-cap spacers (and if it's slightly small, just add something into the end-caps to hold it snug)

Print the magnet arms and glue magnets in them, as well as in the base (oriented so that they are attracting each other). Once the glue sets, glue the magnet arms onto the base (And rotate the base magnets out of the way so that the arms aren't pulled by the magnets as the glue sets).

Print the wall-spacer of your choice (pick one based on the wiggle room in your gear base), side arms (pick one based on whether or not you added extra spacers) and the end cap decor (optionally).

(If you are adding the end-cap decor, just glue it on however you think it looks best)

Mount the center of the base to the wall with the spacer behind it, so that the tilt of the spacer counteracts the tilt in the base caused by gravity.

Screw on one of the end-caps, then carefully add the hourglass, and screw on the other end-cap to lock it in place. Once the caps are secure, screw in the side arms to make sure the hourglass isn't gonna come loose.

And you're done!

PS: You might also be able to just assemble it fully before mounting it to the wall, by rotating the base to reach the screw holes. However, I'm a bit worried about breaking the hourglass while reaching past it, so I prefer to build it on the wall.
