This is a 3DVerkstan style shield (6 hole punch) designed to work with a Welch Allyn Otoscope, a popular otoscope that provides good viewing of the inner ear. Similar to our other designs, we made this shield because the use of an otoscope places health personnel very close to a patient due to the nature of the device. Therefore, this shield was made to help protect the observer from potential COVID exposure. To the best of our knowledge, a shield for an otoscope has not been made as of the date of this submission.

This shield prints in 3 pieces and can be quickly assembled in office. On a Lulzbot TAZ 6 at PLA settings for high speed (0.380 μm @ 20% infill) with supports, the three pieces print in approximately 48 minutes. (Higher speeds can be used though this has not been validated as of the time of this submission). As mentioned above, the shield itself uses a 3DVerkstan 6 hole punch transparancy, thereby maintaining "standardization" with other Verkstan designs. The utility of the shield does not substantially interfere with the use of the otoscope (as validated by our physicians) when oriented correctly. The shield does require a small hole to be cut in the shield so that the viewfinder of the otoscope sits flush.

The attachments have been designed to be a tight fit so you will need some hand strength to get them together. A hand tool may make this easier if needed. The design is also removable as well should that be needed. Finally, the design can stay on the otoscope and not impinge on the ability to recharge the unit in a standard welch allyn well charger.

When printing, parts should be oriented flat. Supports are recommended for best / reproducable fitment.
