Added a hole for a M4 Nut to the Guide and a hold for a M4 bolt to the Brace.
You will also need two 608 bearings (can also be found in old skateboard/longboard wheels)
These are the ones that I used - https://smile.amazon.com/dp/B07JJ1SKL4?psc=1&ref=ppx_yo2ov_dt_b_product_details
Update I changed the bolt head on the brace from a hex head to a circular head
Update 2.0 I added a mount for horizonal orientation
The author remixed this model.
