The stand is made up of two pieces and is designed for modern smart phones of various sizes. The stand holds your phone at a convenient angle and will allow charging with most charging cables with the phone vertical or horizontal. No more propping up the back or front so that you can see your phone! It will accommodate most phones at least 2 1/4" wide and 1.5 cm (slightly less than 5/8") thick or less (including case). These stands can also be used for most tablets, though it is a bit narrow for them to be ideal. These stands are designed to be made from PETG. PETG is a durable plastic that is resistant to heat and sunlight and has the elasticity necessary for the two pieces to snap together properly. We do not recommend making these from PLA as the tension tabs may break.
