53mm diameter cylinder

I created this cylinder to fit inside a typical bore for a door knob when replacing interior doors. the hole on the door is 54mm. i created this in Fusion at 53mm and change.

it fits snuggly in the bore. the main purpose is to align to doors together when replacing interior doors since the new door will typically need to be shaved down.

very basic. 20% infill was strong enough for me to twist into place and use a little force behind it. it worked like a charm.
