Third iteration of the display stand arm. It's a more simplistic design that doesn't use screws/nuts at each joint. The tolerance between joints generate enough friction to hold up lightweight models.

Custom bases can be made by dimensioning the hole to 5mm (base peg is toleranced to 4.8 mm)

Required parts:
x1 Base.STL
x1 BaseJoint.STL
x1 3mmJoint.STL
x2 of a either Arm.STL 50mm or 65mm variant

Doesn't Matter

0.2mm

Post processing may be needed to fit the base joint to the base plate.
