Hi, I will tell you the story of this design.
After some uses, the Z spindle motor holder from my cnc 3018 was broken. I decided to search in thingiverse for this replacement. I have tried all models found for this CNC but anyone worked for me. After 0.500 kg of PLA wasted, I decided to design a replica for my cnc with a little improvement that consist on using 2 screws to hold the splindle instead of the one used in the original design. I think that this improvement is important due to now, there is no important mechanical stress in the hook.
So, here is my design. I hope you find it useful, as I wanted to found this design in thingiverse.
