Align
The Align tool in Tinkercad is how you center the cylinder. If the hole is off, the rod binds.
Live geometry
Change cube size, hole diameter, and axes. This is the same part you will build in Tinkercad before camp. Units are millimeters. Stay in millimeters so everything scales at camp.
Connector studio
Same object as the pre-camp CAD. Change a number. Watch the part.
The Align tool in Tinkercad is how you center the cylinder. If the hole is off, the rod binds.
Select cube and hole cylinder. Group. You now have a real engineered part, not two shapes stacked.
Name it FirstName-Connector-v1. If you change the hole later, save v2. We will look at both.
