Answers.Body: <p>Lego bricks are not sized similarly in each dimension. The height to width ratio of a brick is 6:5, which means that 2 bricks stacked on top of each other with their studs up are 6 plates high, but the same 2 bricks stacked on top of each other on their sides (studs facing sideways) are only 5 plates high.

  If you'd like to keep your build studs up and avoid dealing with the 6:5 ratio, you could try to use [Plate, Modified 1 x 2 with Arm Up](https://www.bricklink.com/v2/catalog/catalogitem.page?P=4623b&name=Plate,%20Modified%201%20x%202%20with%20Arm%20Up%20(Horizontal%20Arm%20Length%205mm)&category=%5BPlate,%20Modified%5D#T=C) with the already mentioned [Brick, Modified 1 x 2 x 5 with Groove](https://www.bricklink.com/v2/catalog/catalogitem.page?id=90291#T=S&O=%7B%22st%22:%224%22,%22ss%22:%22US%22,%22rpp%22:%22100%22,%22iconly%22:0%7D), as the 3.18 mm bar will slide in the groove just fine.
