FTC Tetrix Mounting Block

thingiverse

Unhappy with your perpendicular Tetrix mounting options (inside C)? Came up with this marvel of technology as a simple solution for mounting channels to one another. The original is the larger version. It only has a single orientation, intended for use with 1.5" 6-32 screws to mount the block to the channel (all the way through with a nut on the end) and then you can use short screws for attaching your other piece of channel. With 4 screws in the bottom and 2 long screws all the way through, i'm unable to budget the connection, so seems pretty robust. Made the smaller version to see if it would work well enough and print in a fraction of the time. Results were positive on both fronts. Per my extensive testing of screwing two channels together and trying to pull them apart by hand, the short block passed the test just as well as the big block. I only have some fairly short Tetrix channel at my house, so testing with longer channel and more leverage is TBD. Would love feedback on how much stress these things can take. Planning to add a version with thread in holes on the side for those that don't have 1.5" long screws at hand. UPDATE: Added an updated contour block with smaller holes on the sides for mounting into. This means using shorter screws that thread into the block instead of longer ones that pass through. We started using these in our robot and found really quick that it was more of a pain to use the long screws (plus we have a bajillion short screws). Enjoy!

If you get good stick on your print medium, feel free not to raft.
