Tablet PC stand for a tripod - Lectern

Pad holder 200x200 mm for a standard photo tripod . Printed to put the tablet when playing guitar. To use less plastic the spider web and spider were cut out. On the back it is a 1/4” thread of 5 mm deep. The depth was not enough for screw, so the center of the spider is a little out. Better to increase the thickness to 6mm or make a through hole or make a washer.
