VaseMode PhoneStand

A strong sturdy vase mode phone stand printed with .8mm line width (with a .4mm nozzle)
You can scale the Z size to set the phone stand width to whatever you want.
20mm will work barely. 80mm works great! 40-60mm should be good enough for most.

2 sizes - 12mm or 17mm (gap for phone fit on bottom)
each size has 3 versions. 2 short & 1 tall
17 fits iPhone 11 with Otterbox Defender case
12 fits iPhone XR with a thin decorative "Bodyguardz" case

PLA
vase mode (spiralize)
.3mm layers
.8mm line width (with a .4mm nozzle)
NO top
NO bottom
NO support
need a BRIM

If you print it in vase mode with .4mm line width it will be too flimsy.
.6mm line width might work. I only tried .8mm.

made with Tinkercad "bent pipe" shape
