Model origin

The author remixed this model.

Differences of the remix compared to the original

I reduced the total material recquired in the break-off handle making it a skeletonized design. Print time is therefore reduced by *about* 50%. The breakoff groove was also slightly enlarged to allow for easier snapping once inserted. No changes were made to the key grooves itself, only the handle.
