Valve Stem Cap w/ a D

In my slicer (Slic3r), it works seamlessly for me, but I'm not entirely confident that it will function flawlessly for others. If your slicer displays the bottom layer as a solid mass with no holes to screw on, try trimming off a few layers at the bottom in your slicer. This was a direct request from a Reddit user. Update: I've printed two shorter versions, one of which features a subtle curve simply because it seemed like a fun idea. The two example gray short models were printed using 0.2mm layers, while the pink model employed 0.15mm layers. The shorter versions don't always print perfectly and sometimes require reloading in your slicer to ensure proper printing. However, if you're looking for simplicity, just print them in black - who cares, right?
