Based on original design: Nozzle torque wrench by Anders Olsson


For use with Olsson Block Nozzle Torque Wrench available at the attribution link above.

I created new innards for the torque wrench by Anders Olsson that allows you to use a 3/8" drive socket rather than a 1/4" drive socket.

Socket locks in tight and shouldn't fall off. Fits in the original Torque Wrench body. I also modified the wrench to provide a bit more torque than the standard by increasing the central shaft diameter and thus shortening the fins and making them more rigid.

Materials and methods

I printed this with PLA with 100% infill and 0.1mm layer height on a UM2 printer using 0.4mm nozzle.

I've attached a screenshot of my Cura 2.6.2 settings for this print. Note: I changed the Infill and Skin overlap percentages for added strength.

See linked post by Anders Olsson for more printing information.

Nice! :-)

I was actually looking for 3/8" drive 7 mm sockets when designing the torque wrench.

but they it turned out quite hard to get as single pieces for a reasonable price in Sweden.

So I ended up with the 1/4" drive even though it made the design a bit less robust than I would have preferred it to be.
