I have 2 macbooks on table, old 13" 2012 (magsafe 1) and new 16" 2023 (Magsafe 3), and i just fixed their chargers to table, so they are always connected to power and ready to use. But problem is that since they are magnetic they attract each other too, so i made myself small TPU ends to cover them. Fits nice, does the job.

I printed them in TPU, 0.16 layer height, 100% infil.
