The concrete cup warmer

Hello, I printed this concrete cup warmer, which is quite simple to make.

To make it, you will need some M4  and 4x M3 screws , which are not ideal; it would have been better to design it with clamps but I had never made a mold before. Be sure to sand and lubricate the walls before pouring.

I didn't succeed in removing the piece from the mold on my first attempt. I had to put the mold in the oven to soften it. I think PLA would be more suitable.

I also made a mod that allows you to stir your coffee, as you can see in some of the pictures, but for now I'm not satisfied enough with the result. Feel free to contact me if you want the extension anyway.
