Tested the rack2020 today everything worked great except the video which is blurry
You are looking at about 2kg of hips and 20 bearings printed in Nylon. The bearings were printed on a MH Pulse the Hips Gears and brackets on an Anycubic Chiron. All are printed with a .8 nozzle. Here is a link to the parts
Here is a link to the rack on the build plate
And here one of the bearing holder plates
So much for all the comments I heard that one cannot print accurately with a .8 or FDM is not up to the task to get center distances right.
