Hex Nut Encoder Adapter (3D printed)
- Material: MJF Nylon
- File: encoder_adapter_v0.stl
- Qty: 2

AMT10 Encoder Mount (3D printed)
- Material: MJF Nylon
- File: encoder_mount_v3.stl
- Note: The mounting holes for AMT103 where too large for the M3 Philip Machine Screws. A small amount of glue was used to shrink the holes. Version 4 should resize the holes to be 5-10% smaller (2.7mm) than the screw diameter(3mm). Also, the length from the mount surface to the motor shaft should be 56.5mm not 55mm.

AMT103-V (Rotary Encoder Incremental Programmable Quadrature) amt103
- Qty: 2
- Supplier Link: https://www.digikey.com/en/products/detail/cui-devices/AMT103-V/827016
- Default Resolution: 2048 (qppr) (2048 is Maximum)
- Resolution
4*ppr*gear_ratio = Steps per wheel revolution(4x2048)*(80/11)=59578.1818182- `2pir
- meters per rev = 0.7979645340119
- step per meter =
step/rev * (meters/rev)^-1 - steps per meter = 74662.6939905
- 59578.1818182 Steps per Revolution (59,578)
