Summary

Clip that holds the legs in place when the workmate is folded up.

Instructions

Knock out the pin that holds the leg in place and remove the broken clip.
Print out the two halves of the new clip.
Spread some glue on the bottom half of the piece including around the hole, insert the rod and push together so both halves align.
When dry fit new clip and re-assemble leg and pin.

N.B. Super glue seems to work really well with PLA not sure what would work best with ABS.

Two reasons for printing this in two halves.

It would have meant a bodge to get the bottom pin correct.
I think if the top of the clip is in two independent pieces it has more flexibility and is less likely to break.
