The best way to protect yourself against COVID-19 is frequent hand-washing. Washing your hands for as long as 20 second.
This is an hourglass that counts twenty seconds for you.
Direction to use:
After printing the parts fill the cap twice (up to the line inside the cap), with salt or sand or similar particles (preferably colored ones ) and pour it inside the hourglass.
Put the cap on the hourglass and you're done!
Print instructions
It's best to print this with SLA printers, but I have printed it with my PRUSA MK3S (FFF) and the print is fine.
No supports required.
