PwnCNC is super excited for a partnership with 80/20 to provide three kits for the Shapeoko 3 CNC’s using their 1×3 Aluminum Extrusions.
The PwnCNC Extrusions-Bed Upgrade is available in 3 sizes and includes everything you need to attach the extrusions to the front and rear plates of your CNC machine.
What’s included:
Standard:
- (9) 22.853″ 1×3 Aluminum Extrusions

Extrusions and hardware are drop-shipped from 80/20. The optional extrusion plugs are shipped separately from PwnCNC. Typically takes 3-4 weeks of processing on the 80/20 side then a 1-4 day shipping.
A special add-on is mentioned in my blog article… End and center extrusion joiner plugs. These 3d printed plugs help prevent twisting and makes installing extrusions a breeze.
If you’d like to print these plugs yourself, download the 3d files here: https://www.thingiverse.com/thing:4081383
