Spiral hourglass designed for an SLA printer, designed in Fusion 360 (It has so many curves that the program sometimes freezes up).
F360 archive file is included.
I used this tutorial to help me:
The main pieces were printed on a Formlabs Form 1+ with Clear V4 resin. This model is a bit tricky to print as one piece (you can see the attempts in the 2nd photo), so I split it up. Its easier to print as two identical halves with a joining pin in between. The .form file is included with the orientation and support placement I used (its better not to have any supports on the inside as they are hard to clean up).
The top and bottom covers were printed on a normal FDM printer (Blue ABS on the Zotrax M200)
Dont worry, I will make a video of it with falling sand, I just need to find some :P
