I've been able to print the latest changes and im extremely satisfied with the results.
I have changed up the tie downs a bit to add some more clearance. I even made some (untested) models with the HicWic universal mount in mind. If anyone wants to try them out. Enjoy :)

NOTE:
I've made some improvements to the design, to add better printability. i round
