This is a 3D printed robot arm based on Ikea Tertial lamp.
I use lamp because it has very good kinematic with using springs to unload servos.
I cut all beam, but you can use any length.
It has 5 DOF and use 5 standart size servo.
You can find list of all components and printing part in BOM.
It cost about $60 for me and use small amount of plastic. I haven't done any instruction yet, but I will be happy to answer all your question.

Now I am trying to make some isntruction and new code to use it in cartesian coordinate system

You can find STL files at Thingiverse

Lifting power test video:

Distance between base and attaching point: 500mm

Weight: 0.5kg

Lifting power of Tertiarm depends on configuration of spring. In this test I use 4 standart Ikea springs.
