My buddies table decided to explode and the middle leaf of the butterfly table collapsed. We looked everywhere for new guide blocks online and could not find them. In the pictures I've included you can see what the destroyed version looked like. We spent some time designing this new block from scratch and it works well. My buddy now has a fully funtional butterfly table! I hope this helps you when you are about to pull your hair out from not being able to find these.
The author marked this model as their own original creation.
