The file 'Hongdian Nib Unit Storage Case 3D Printer Model' is (stl) file type, size is 404.0KB.
When I received some nib units from AliExpress, they came in the translucent holder shown in the picture, however, none of the ones ordered from Amazon did. I really liked the holder, and had someone point out that it could hold both the 26mm nib (typically called the #5 nib) unit and the 35mm nib (typically called the #6 nib) unit.
So I modeled this one, it is very slightly larger in diameter than the original, but I like the way it fits both size nibs (as shown in the pic).
Internally, there are two threads for the nib unit, and externally for the cap is a triple start 1mm pitch thread. I printed this with PLA+, with a 0.4mm nozzle and 0.08mm layer height.
