I just uploaded a 3D printable design to Thingiverse for a Z-Axis dust cover that screws directly to the standoff/reduction plate for C-Beam style machines. Im working on some other designs for accessories that I will be uploading soon. Openbuilds Z axis cover by Hoofty
Printed at 0.2mm layer height. It was too coarse for the lettering, but overall turned out pretty good. When I do the next one for my c-beam lathe project I'll print it at a finer resolution. Has a line around sides at the same height as the top of the screw holes (think I need to either install the tl smoothers or play with the jerk settings.
