VERY nice design, TY!
Had to print @ 80% scale to fit my Soprano Ukulele.
Would NEVER use it without some rubber attached, so that the Ukulele will not move anymore. Otherwise this would be very slippy.
As info: You want to print this rotated by 93,8° to be laying flat on the print bed. Also, I had to switch the surface orientation of the model.
