When working from home I use my work laptop for development, but would still like to sit at my desk and have access to my personal rig. This an easily printable mount for a laptop to allow just that. It integrates nicely into my clampables accessory clamp.
I have a 15" macbook pro, and it fits perfectly. I use PETG so there is a very slight flex to it giving almost a suspension like effect. Not enough to cause problems but enough that it should last quite awhile and support weird accidents.
As with my digitizer easel, the parts separate and sorta fit together for storage. This one doesn't have dedicated slots to hold each part as that would add too much bulk or remove the needed strength to support heavy laptops.
I have a .8mm nozzle and I printed the rod and bolt at .2mm layer height, and the main body and arms at .4mm layer heights.
