Lab Rax Extension Side Panels & Post Joiner

To expand the Lab Rax system beyond 5U, you'll need to print out a second set of vertical posts (4), add a set of side panel extensions (2) and join them with the post joiners (4). This model includes the side panel extensions and the post joiners required to expand your Lab Rax system.

You can't use two sets of the original side panels (5U + 3U for example) because they are slightly oversized to slot into the top and bottom edge pieces, so they would be too long when combined. These expansion side panels are shortened just enough to be used with an original set to make a complete set that is the correct height.
