Phone stand

medium tier · create

The request

Design a desk phone stand for a phone about 75mm wide: a tilted back rest around 60-70 degrees, a lip to hold the phone's bottom edge, and a stable base.

What the AI judge checks

  • A back rest that is tilted, not vertical and not flat
  • A lip along the front edge that would stop a phone sliding off
  • A base wide enough that the stand would not tip with a phone on it
  • The rest is at least as wide as a 75 mm phone
  • One connected body with no floating or detached geometry
  • No decorative or unexplained features beyond rest, lip and base

Measured checks

  • wide enough for a 75mm phone
