# Build Tips & Tricks

## Compatibility with 2024 FTC Starter Kit V3.1

An additional item was added to the FTC Starter Kit V3.1 during the 25-26 season, the [5mm Hex Bearing Block](https://www.revrobotics.com/rev-41-1683/). If you are wanting to reuse your FTC Starter Kit V3.1 from the 2024-25 season you will need to order two 5mm Hex Bearing Block.

## Adjusting Lap Corner Bracket

When building with 15mm Plastic Lap Corner Brackets the short side nut should always be tightened first before adding the screws in the long side as they block the short side nut. If you find that you need to adjust the short side nut after you have already installed the bracket, you are able to remove the middle nut and loosen the other long side nut then tilt the middle screw to give you enough access to the short side nut to loosen or tighten it.
