A simple cup holder that can be placed on any wall.

Features a locking mechanism to support heavier drinks and insets for standard can and bottle sizes.

Required hardware:

• 2x - M3 x 4mm countersunk bolt (any M3 bolt or set screw will work as long at the total length is less than 5mm)
• 2x - M3 x 45mm bolt (30mm and up will also work but will be weaker)
• 1x - small rubber band
• 2x - countersunk drywall screws (I used #8 x 1.5in, but 4mm will also work)
