During the french cup of robotic, I had to bring my Mac mini to program the robot and to print parts with Cura. I didn't want to just put my Mac on a table with all the drills and soldering iron around and not to mention the number of people who would turn around ...So I created this Mac holder which can be attached to a screen with two screws. It works very well and I use it since 5 months without any problem. To turn on the Mac, there a place under the part where you can touch the on/off button.You can print it very fast because it will not be see and with a density of 20% without any problem. The only inconvenient is that it still takes 6 hours to print at 50 mm/s ...
