Slide nuts and nut spacers into the OpenBeam extrusion's T-Slot.

Each stack should start and end with a nut

THere are 23 nuts and 22 nut spacers.

We intentionally cut the nut spacers slightly undersized (on the minus side of tolerances). As you install the nuts, subsequent nuts and spacers downstream will move slightly and “fix itself”. If we didn’t do this, we’d end up with an interference situation (if the parts came in on the plus side of tolerances).
