Skeleton Key (full inside)

thingiverse

I tweaked lardcanoe's skeleton key design to create the tube filled object. Using Tinkercad, I added a cylinder in the middle and rotated the file so it rests on its side. To make it stronger, I printed with 100% infill since the old locks need it are very rusty. Additionally, I used supports for the tooth at the end to ensure it would be okay.
