Fire extinguisher
The fire extinguishers are made in such a way that they first have to be pulled up a bit before they can be turned to the left or right. In the down position they are therefore blocked. This is to prevent the fire extinguishers from being accidentally activated. The black caps on top are printed with red transparent PLA and then sprayed with black paint. The letters of LEFT and RIGHT were then sanded so that the red reappeared. The small print is colored with a white marker. In the STL zip you will find a readme file with everything you need.
