Tube Rings with counter-weight for Skywatcher 150pds Telescope

Tube rings for my telescope with a custom little counterweight to try and offset my camera/focus weight. Fits my 150mm Skywatcher 150pds tube. 

Depending on padding material used, you might need bigger or smaller ring-diameter, but even the thicker material I used could be fastened properly when tightened. I used padding foam leftover from packing material in other parcels. 

I would not trust it to carry heavy equipment without testing properly first! My counter-weight is only about 300g.  

Printed in 0.3mm PETG, 15-20% infill.
