Modifications to a nice design.
- Added suitable clearance and alignment to all card slots; can now print without scaling.
- Added ridges to the side of lid for a more tactile feel and easier removal.
- Added a snap-fit connection to both halves to secure the lid and stop it accidentally coming off. Also added chamfers to help with insertion.
- Added "SD" logo to top of lid so it is easy to tell what's inside and act as a visual indicator for which end to put over the micro-SD section.
- Added some styling to front face and chamfers to the top to round it out.
