2021.12.10 - News and Updates

Welcome to OpenOcular’s first newsletter and thank you so much for being part of the community! Today, I am excited to finally release OE-2 as a free downloadable, 3D printed microscope to smartphone adapter! Our goal is to widen the capacity to document and communicate microscope data for the vast majority of students and professionals in science who do not have access to expensive, high quality camera equipment. We hope this tool along with the ability to print this design at no cost will open new avenues for anyone to engage with and become inspired by the marvelous microscopic world! 

For those wishing to support this work, OE-2 is available for purchase and is home grown with quality guaranteed. Purchases will help out tremendously and go directly to design development, donations to education, and further outreach. With your support and feedback, we aim to continue shaping new designs to bring the best printable ideas so stay tuned for the latest.  

To download OE and learn more about OpenOcular designs, visit OpenOcular.com. OE-2 instructions and support is available as well so be sure to check it out. If there’s any additional support needed, please don’t hesitate to reach me at josue@openocular.com.
