MacAir laptop computer security bar, lockable

A lockable security bar for laptop computers, especially the Apple MacAir M1 laptop computer that doesn't have a built-in lock. You'll need to buy a lock and cable system to add to this design, which in its original form fits the Griffin TechSafe system that I used with my old macair, but you can modify to fit other lock types and other laptops.
I printed in three parts because my bed wasn't big enough to combine the left and middle sections into one. You might want to fuse those into one stronger piece instead of screwing and glueing them together. The right-hand side slides over the metal clamp that comes with the Griffin lock system as you mount it on the laptop.
