My workplace is still operating during the coronavirus situation. To make it easier for everyone to disinfect hands after touching doorknobs, I created these wall mounts for 8oz Purell pump bottles. I hope these are helpful for anyone else who is not allowed to telework! I attach them to the wall using two 5lb 3M Command Strips.

There are two .stl files attached:

• "v3" has criss-crossed walls and prints as-is fine without supports. It took about 2.5h with the fast/draft setting on the Lulzbot. The fit is snug, but you can scale the .stl if you prefer a looser fit
• "v4" is more minimal and printed in just 1.5h on the fast/draft setting. I rotated the .stl model 90degrees onto its back and did not use supports. There was some drooping at the top bridge, and the "Hand Sanitizer" engraved text label came out poorly. The item was adhered very tightly to the print bed, but I managed to pry it off. But despite all that this item functions well with minimal print time! I imagine using a thinner layer height and speed would have allowed for better aesthetics. FYI the v4 horizontal cross-section is hexagonal like the Purell bottles at my workplace, so other brands may not fit without editing/scaling the design.
