Telescope Tube rings 240mm

Those tube rings are specifically made for my Hand made Telescope which was missing Tube rings. As a way to mount hings to it, I decided to use countersank M6 bolts.
Those are slightly to small for the bolts themselves which is intentional so you can use a soldering iron to push them in all the way. 

The Screw holes are strengthened in the slicer with two additional walls.

I made M6 screw heads which work perfectly with this model.

Make sure it holds your Telescope with small tests! I'm not taking responsibility if it falls.
