This is my last entry to the 3D printing nerd Speake cover contest. The base is the same I used on my other entrys, but this time I tried to make the central grid movable. The objective is that when you pull the central pin the whole thing moves with it. I don't know if the system works properly , because I didn't had the chance to test it, but it went really well on Fusion 360 and also on the slicer. I used a 0.2 mm accurancy so every thing that should move has a space of 0.2 mm between each other. I recomend to print it on a 0.2mm resolution or higher, use a printer with a really accurated filament flow and, in the slicer turn on the setting "print thin walls" or similar (depends on the slicer). If there is some problems with the design please let me know and I will fix them as soon as I can. I left the original stl file for printing and I also left where the file that shows the result after moving the whole thing. #3DPNSpeakerCover
