Ashtray Sandmold

What it is

A sand mold to create a temporary ashtray, including a captive sieve/strainer to separate and transport cigarette butts.

Why, seriously

Cigarette butts are the most littered man-made waste item in the world and are simply a disgrace to find in a nice place where you intend to sit down.

Since the filters (cellulose acetate) rather than any ash or left over tobacco are of concern, this design aims at them not being left in the sand. The sand itself is stil used as heat resistant material for an ashtray. → Maybe giving the inclined user a nice and easy way to discard the cigarette butts properly later on helps to keep places clean.

For everyone more interested in reading about the problem rather than printing the item:

How to print

Recommended for printing is a 0.2mm layer height. Material at one's discretion, I opted for PETG because it tends to be nice and warm when I am at the beach.

Preferably generate the sieve by using a modifier in the slicer. Besides having a choice of style and hole size, printing will run much smoother. - A hole size of around 5mm seemed fine to me.

How to use

Grab your sand ashtray mold from your collection of beach toys.

Create a temporary ashtray with the sand mold.

Use that ash tray as any other one and collect the butts in it.

When leaving the beach: 

• Put the mold on top of the used ashtray
• Slide the sieve in place, effectively cutting the complete sand tray off of the ground
• Shake & sieve to separate the cigarette butts from the sand
• Dispose of the butts at the next proper litterbox

What next

Maybe, take a look at this designs cousin to have it as simple block mold and strainer box or scroll through my other designs ;-)
