Ceiling distance holder

This is a Holder for something that shall be mounted to the ceiling of a room..or anwhere else , hanging DOWNWARDS from there.. probably you can also use it as a standoff from bottom or from wall. I can be fastened with ONE screw ..5mm dia INSIDE the tube,

I added 2 versions with a 40 by 40 mm base and a lenth of 100 and 50 mm . Opposite to the base there are 2 slots for attaching straps or wires or the like.

If you like , you can also use teh Freecad ( 1.17 ! ) files and modify furter
