i found this one [
www.thingiverse.com]
problem is that it does not say how to hold the e3d in place
and the onshape link does not include a fan duct, i exported from onshape to step file so i could import it in fusion360
and the files on thingiverse have the fan duct and base combined so i longer longer can mill MDF and bolt on the duct
are there other know effectors for the e3dv6 ?
