I wanted a nice vertical stand for my Lenovo ThinkCentre M70q Gen3 Tiny PC. It also fits the M75q Gen2 and sure it will fit other Lenovo ThinkCentre models as well, but I didn't test it.
It has a nice Lenovo inspired Logo in the middle section and two springs, which are designed to hold the stand and the ThinkCentre PC together when moved around. It doesn't need any support to be printed!
