Hello! I am in the process of building my maslow (I got the original M4 kit through kickstarter but didn’t start assembly until I got the 4.1 upgrade recently 
) and wanted to share another dust port design for 3d printing.
I did at first print the not shop dust port but found the bolt tabs on the acrylic end weren’t stepped for the thickness of the acrylic and also I wanted to make a shroud that would lock into the channel of the sled. I only slapped this together pretty quickly and happy to find it fits really well first go, thanks to hardware design files being available for the project.
This .step suits vacuum hose with 1.5" internal diameter however if you have fusion360 the port size can be updated by modifying the sketch shown in screenshots below.
(I actually can’t upload the design files because I just joined the forum, I will upload to thingiverse and drop the link shortly)
