Flattened top and bottom and hollowed version of fbutkovich's brilliant design!
It can be used in many different purposes. Very easy to print since no sd logo carved on top and bottom surface. No need to use support.
Good looking and handy. Have a good print!
Notes:
If you're planning to acetone smooth your print, you may want to cover threads. Completely optional but just to be safe.
The author remixed this model. Imported from Thingiverse.
Hollowed model for more common purposes and erased SD engraving.
