for better grip maybe you can try printing two sections to silicone injection molding

I can test your part with my printer and give you feedback on tolerances

The quality depends mainly on the production process, the FDM process is good for the production of Lego pieces , but it takes a bit ' of work to get good results

Ok, so, first of all, have you experience with 3d printing and software (like cura, mattercontrol or simplify) ? I don't know that printer, but I can give you some tips and tricks for the FDM printers in general.

This are the measurements which I use --> Step1 by Marco Uaz, su Flickr

I like the wheels, maybe you can add some details like hex nuts, i am working on something similar https://flic.kr/p/HjZRZm About the print i have an advice for you, use this measure for the cross hole, I use them for FDM/SLS/SLA printers and the results are very good https://flic.kr/p/HqxExd Sorry for my bad english

WOW! Really nice work on the crane's parts
