This is a discreet holder for earplugs to be mounted on a motorbike handlebar to easily stow and retrieve foam earplugs. The open-bottom design allows easy storage of foam earplugs simply by pushing them through the bottom gap. A cutout at the front allows for simple retrieval of the earplugs when it's time to ride. 

The open bottom in theory also ensures good airflow of your earplugs while also protecting them from the elements while you're off the bike. Note that this is not intended as a long-term storage solution because the earplugs will be open to other contaminants/insects/mould over time however, you should be swapping out your ear plugs regularly anyway!

Printing was achieved successfully without supports in an upright position and with front face down using the following settings:

• Layer height: 0.2mm
• Supports: Not required unless your printer has major bridging issues
• Nozzle: 0.4mm
• Material: PLA (any old PLA/ABS/PETG will do as there is very little strength requirement)
• Adhesion: Brim when printing in mounting orientation. Brim not required when printing outside face down

Happy print and ride safe!
