After we finished our pipe object, now we will try to add its faucet spindle with a little help from metaball feature. I want to make it quick so let’s just start it, alright?
Open your last blender 3d practice file that have pipe object, change the viewport to top viewport, and create a metaball with shortcut: Shift + A choose Metaball —> Capsule. To minimize capsule radius without change its length, set the radius parameter to 0.2. You probably have a different radius value, it depends on the size of your pipe. Just make sure it has the right proportion.
