Lenovo Think pad T590 laptop stand but should work for some other models in the T line up.

If you want you can add thin lining on the inside (cork, foam, leather, cloth etc.)and add rubber feet on the bottom to avoid slipping.

My print settings:

• 20% infill

• 2 walls 

• layer height 0.20

• adaptive cubic pattern 

Printed on my K2 took about 3h to print on standard speed. Turned out better than i expected i like it but i will be doing a improved version.
