Now here’s a challenge…..

If they're soft enough, they may work as a cleaner for your metal files.

Stack a few of them to make them thicker and use them as softeners for jacking your car. Or just normal softeners for rigging.

Softeners for lathe chuck jaws and vise jaws.

Vibration dampeners for tool legs (lathe, air compressor, grinders, etc.)

Use them as sacrificial backers for drilling.

Connect about 20 of them end to end and make a new gasket for your garage door.

Drill a bunch of 1/4" holes in one and use it as a secondary strainer to keep all of your wife's hair out of the shower drain.

Ghetto holders for bars of soap.

Melt a few of them together and make a sweet set of Crocs.

Put them under the feet of <insert heavy thing here> and use them as sliders to prevent ruining your shop floor.

If they're different materials like TPU/PET/PC, each has a different melting point. You may be able to use them as terrible tempilstiks for welding.

Use them as gasket material for junction boxes.

Use them as grippers for hard to open bottles.

That's it. That's all I got.
