MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
This was printed in PLA before reading the description about this being of ABS design. Cards don't fit by quite a bit.
Edit: Just learned that the SD card is sitting on the MSDuo blade, making the STL 4mm slimmer then it would be for the SD card. The SD card blade is sized for 24mm wide. The Micro SD card can nearly fit into slot.
