Problems with 20/20

[HannahtB]

On Wednesday our team received a shipment of 20/20 to build the frame of our robot. This is a normal thing for our team. This year our shipment came on time but the measurements were off. The diameter of the channel was .5 millimeters too small. Which would be usable except for the fact that the inner channel is also .5 millimeters too small. This means our sliders won't fit. We decided that we needed more sliders anyway and looked into getting more. They don't make any for the channel we got. Is anyone else having this problem or one similar?
