The submission process
----------------------
Please submit your proposal at 
https://pretalx.fosdem.org/fosdem-2026/cfp before 5 Dec 2025.

Select the "Open Hardware and CAD/CAM" session. Please note that the 
"Open Source Design" track, while a lovely group of wonderful hackers, 
is not the same. :)

Please include the following information with your submission:

- Abstract
- Preferred Session length
- Speaker bio
- Link to any hardware / code /slides for the talk

Fill in at least a title and abstract for the proposed talk and a
