The optics of astronomical reflecting telescopes must be adjusted exactly.
Many people use alignment lasers for this purpose. Of course, the laser itself must be centered just as precisely. My laser was badly adjusted at delivery, so it had to be adjusted exactly first.
For this I designed the model.
It is printed in two parts to avoid supports and to get exactly round bearing guide axes. The parts are simply plugged together with the dovetail guide.
I printed the parts with eSun ABS+ Black, but any other material will work just as well.
You may have to vary the flow rate to get exactly 8mm axle diameter.
You can use the 8mm test model to adjust to get the correct diameter with little material. If necessary, you can change the diameter in the Fusion360 project.
You will also need 4 608ZZ ball bearings (8 x 22 x 7).
Have fun!
