This is a simple, elegant wall mounted rack for storing table tennis balls.

The balls are held securely and won't be dislodged by wind if, like ours you have them stored on a verandah, but they are easy to remove and replace one at a time.

I do recommend a little support as shown in the attached print file, and if you print in the upright position as shown, print time is quite lengthy for the small amount of material used.

The end result is worth it though!

The version shown is printed in PETG as it is in a semi-exposed location, however the attached gcode is for PLA.  Either will work well.    Mine was printed with a .4mm nozzle Prusaslicer 0.20mm QUALITY mode.
