FTC Tetrix Mounting Block

thingiverse

Unhappy with limited Tetrix mounting options inside channels, created this innovative solution as a simple fix for joining channels together. The original design is larger, intended to work with 1.5" 6-32 screws that mount the block to the channel through nuts and then secure other channel pieces with short screws. With four bottom screws and two long screws all the way through, the connection appears robust. To test performance, created a smaller version for faster printing and more versatility. Results showed both versions successfully passed manual stress testing, where two channels were screwed together and pulled apart by hand without failure. Further testing is needed to determine performance with longer channel pieces and increased leverage. Welcome feedback on how much stress these connectors can handle. A new design with threaded holes on the sides will be added for users who lack 1.5" long screws. UPDATE: Designed an updated contour block with smaller side holes for mounting, requiring shorter screws that thread into the block instead of longer ones passing through. This change proved beneficial during robot usage, as short screws were easier to use and reduced problems associated with long screws.
