Column cover for mini mill. Several versions depending on if you want a press fit, fit with active retention, or have an air spring from LMS installed. Has a basic end stop but being 3d printed it is not super robust if you really cranked on it. Does cover the top of the column nicely and will not slide off like the factory verison. May require some minor filing for a perfect fit.
For the retention plugs I used M3 screws and heat set inserts in the plug. Seems to be plenty strong for a 3d printed part.
The author remixed this model.
Original file was used for basic shape. No more overlap on column. Also has active retention so it cannot be easily pulled out.
