Heavy Garden Door Stopper Concrete Mold

I needed a garden door stopper heavy enough to hold the garden door when it's too windy and not too ugly at the same time, so I designed a concrete mold.

I used a 1:3 mix of cement and sand and it resulted in a total weight of 10.5kg

I would recommend testing with water before pouring the cement to make sure it's water tight, I had to use a cheap silicone because it leaked which is expected since I used printed screws and bolts.

Once the concrete cured I used PVA (elmer's glue) to seal it stop the dust to fall off.
