Simple plastic nut to hold table in position, designed an equivalent to replace the one that was lost.
This spins on to the 5/16 bolt to hold the table in place. Print it in place no tapping is nessesary as the threads are printed in and adjusted slightly so that it is not too hard to spin on the bolt but has enough friction to not easily fall off like the original.
The author marked this model as their own original creation.
