Secret Diamond Box
thingiverse
This is a diamond box that you can scale to as big as you want to hide stuff from your siblings like I do. This make prints perfectly on a lower speed and more detail. It does not need supports at all. I suggest buildbee for the slicer program because it tells you how long it will take before hand and how much filament you will be using. And trust me, it is surprisingly accurate. It is off by about 2-3 minutes. It will print much smoother if you select the added detail setting and turn off supports.
