Ultimate NozzleBox Tag Hanger for Extrusion Indicators

I finally started getting into swapping nozzles on my MK3S and needed to find a solution for storing my nozzles. I found the excellent Ultimate NozzleBox remix v2 on Thingiverse by ploebb. Unfortunately, my extruder doesn't have a convenient place to put the nozzle tags, so I decided to make something quickly to glue to the center of my extrusion indicator where I can hang the tags.

I fired up FreeCAD and created this very simple object (FreeCAD file included for remixing). I didn't time it, but it probably took me all of 10 minutes to design. See the last two pictures for the dimensioned sketch and resulting object from the revolve operation. (The similarity to a Diabolo pellet is purely coincidental...) I also exported this object as a STEP file for people who don't use FreeCAD to include into their own designs or use as a starting point for a remix.

I sliced this in PrusaSlicer v2.1.0 and include the .3mf file to see my print settings. It was sliced at 0.1mm layer height (first layer 0.15mm due to MK3S firmware limitations). I didn't bother with infill, and only use 3 perimeters. It is plenty strong for it's application, and only takes about 5-6 minutes to print.

NOTE I'll add the FreeCAD file once this site supports .FCStd files... Until then you can find the FreeCAD file on Thingiverse.

Edit (2022-03-30) Realized that I hadn't uploaded the original FreeCAD file as promised. Just added the original FreeCAD file.

Print instructions

Post-Printing
Just glue this to a flat horizontal surface. I used the center of an extruder indicator on my e-axis motor, but I could see off center being an interesting visual choice for the right indicator.
