Notes:

I printed this in PLA at 190°.

It's printed at right angles to the orientation you'd expect to get thestrongest grain. (When I tried printing this with the cone pointing up, ittwisted apart in under a minute.)

Post-Printing

super glue in the screw driver bit.

With the print in its printed orientation, the screwdriver bit fits in so theblade is vertical.
