Laptop Stand (Modular)

This is a simple laptop stand I designed to be modular. This is used for a 13 inch macbook pro and works fine. It does not flex when typing and is fairly sturdy. It also has a couple slots for printing tpu standoffs to keep it from sliding and gripping the laptop. The square slots are 15x15mm

I printed this using Inland Pla+ w/ 20% infill. No supports are needed although it can help to have some around where the nuts go on the back plate.

Note: I used m3x10mm bolt and an m3 hex nut to attach the parts, but when i printed the backing plate the holes we're a bit small and can be held using only the m3 screw/bolt.

Feedback is appreciated.
