Pegboard Soft Flask Holder – Running Hydration Storage

A pegboard holder for running soft flasks. I couldn't find accessories online that fit my AR Shelving PRO metal pegboard and actually held my sports gear, so I designed my own set.

Two prongs grab the flask under the cap collar, so it hangs free and open to the air – perfect for letting the flask dry after washing. Tested with 250 ml and 500 ml soft flasks.

▶ Features

• Made for the AR Shelving PRO metal pegboard (100 × 60 cm panels, sold at Bauhaus / OBI) – hooks into the holes and locks behind the board, no screws

• Holds the flask by its neck – fits 250 ml and 500 ml soft flasks

• Flask hangs free and dries properly after washing

• Only a few grams of filament, no supports

▶ Print settings (what I used)

• Material: PETG

• Layer height: 0.2 mm

• Walls: 4, top/bottom layers: 4

• Infill: 20 %

• Supports: none

• Printed on an Artillery Sidewinder X1, 0.4 mm nozzle

• Bambu Lab A1 print profile included (13 min, 2.5 g of PETG) – made in Bambu Studio, not test-printed on a Bambu yet

▶ Tips

• Other metal pegboards with similar holes may work too – print one test piece first.

• Different flask brand? Check the neck – the gap between the prongs should be slightly narrower than the cap collar.
