Questions
- Where do I get Open Duck Mini STLs?
- The v2 /print folder on the official GitHub repo. megabot links that folder from the BOM when the Open Duck look is loaded.
- Which servo is on the official sheet?
- STS3215 C001 at 7.4 V. megabot will not substitute a different Feetech SKU as if it were official.
