After last week's HUGE (litterally) print, we decided to try again and there it is ! 

A reasonably sized (for most of us) KnotKicker Lace Undoer (name to be changed).

After testing it multiple times, it worked, the ring did go in the slot it was supposed to go last week and it helped us to untie the laces we made with it.

But sadly because of its fragile structure and size, one stronger pull than the others and it broke. So we decided to reshape the whole structure from scratch to make sure that the design would be structurally strong enough to withstand the carefree pulls and pushes of a 10 year old.

Next time we'll see how we can improve the design to better fit a user's hands and be more durable for continuous use
