Toolhead PCBs
Important
These mounts are designed for NEMA17 steppers. There are several off-the-shelf options for NEMA14 steppers:
- ZeroG Discord members can use TurtleCrawler's CANbus 36 mounts
- https://github.com/KayosMaker/CANboard_Mounts

This page contains parts for mounting toolhead PCBs on the back of a NEMA17 stepper. Optional shrouds are used to cover the PCB wiring.
The first half of this page contains mounts for both NEMA14 ("36") and NEMA17 ("42") PCBs. Examples of '36 PCBs are the BIGTREETECH EBB36 and Mellow Fly SHT36. An example of a '42 PCB is the BIGTREETECH EBB42. Variants of each mount are available for both cable guides and drag chains.

PCB Shrouds
These shrouds cover the PCB and wiring for a PCB mount. The 30mm fan is strongly encouraged for enclosed builds.
PCB shrouds come in three styles:
- Stock
- Cat face
- 30mm Fan
The cat face shroud is purely cosmetic and uses the same materials as the stock shroud.
