This thing includes a 52mm Spindle upgrade, or 40mm Laser + X axis cable management + Z axis limit switches.
For X/Y upgrades see: https://www.thingiverse.com/thing:3625249
Quantity 1: 52mm Spindle & Power supply
Quantity 1: 40x40mm Laser
This one is 7W which is more than what is recommended to be used with my CamTool CNC V3.3 board. You might consider getting the 5W version to stay within spec.
Quantity 1: 10cm T8 8mm Trapezoidal Stainless Steel Threaded Rod Lead
This is replaces the 9cm long threaded rod, which has a thread that isn't compatible with the commonly available anti-backlash kits. Also makes it possible to install a hand wheel on the Z axis.
Quantity 1: T8 Anti-Backlash Spring Loaded Nut
Quantity 4: LM8SUU 8mmx15mmx17mm Linear Motion
Note: You can remove the ones that cam in the existing Spindle motor holder - using Bearing_Pusher.STL you can push out the old bearings and re-use them.
Quantity 2 to 4: M3x8mm screws
Qty 2 - Limit Switch model: V-153-1C25
Micro Limit Switch Long Straight Hinge Lever Arm SPDT Snap Action

This is used for creating a cable management track.
