F694ZZ ball bearing 16 pcs.

4x 40mm countersunk M4 screws (gantry)

10x 10mm buttontop M4 screws (motor mounts, corner idler bearing mounts, gantry rail mounts)

8x M4 Nuts (gantry idler bearings)

8x 6mm buttontop M3 screws (MGN12H linear rail)
There are also 2 pins that are 26mm long x 4mm diameter which is placed through the bottom of the corner idler bearing mounts and are what the bearing spin on, and is held in place in the part by the aluminum extrusion when it's screwed down. No idea where to get something like this, but you could always take a 26mm M4 screw and dremel off the head of the screw.
(For the 26mm pins you can use also 26mm pieces of 4mm welding electrode with coating material removed. Or https://www.amazon.com/26mm-6325-Dowel-Alloy-Steel/dp/B01I0BDG06)
