22mm cement nozzle for silicon cartridge

22 mm nozzle for standard silicone cartridge to use with cement.

We live in a over 100 year old building which has some gaps and holes between the bricks of the outer wall. This means sometimes there are mice living in the wall.

It is sometimes not possible to fill small holes properly with cement using a trowel. So i made this slide-on nozzle to use an empty silicon cartridge to press the cement into the mouse hole.

The nozzle should fit on standard 49mm silicone or acrylic cartridges.
