This mini ratchet is sold by Topeak and O'Reilly Auto (branded Power Torque). This 5 hex bit holder is printed from TPU and clips onto the handle of the ratchet. If you use short bits, two holders with a total of 10 bits clip onto the ratchet nicely and are easily carriable in a pocket. I use longer bits for my metric hex drivers, so only use the one holder, though a second holder with short bits would still fit.
The author marked this model as their own original creation.
