One night I was awakened by a crash in the bathroom, and in the morning I saw that a daylight lamp, which was attached to double-sided tape, had fallen.

 

I made a drawing in 3D solidworks

 

After that I exported the model to the CURA program, downloaded it to a flash drive and put it to print on a 3D printer

The result was slightly cleaned with a stationery knife and checked for suitability for use.

Printed the second mounting part and securely fastened the lamp.
Now she won't wake me at night.
