50 mL pH Calibration Tubes Holder

Date March 13, 2024
Designer Caleb Mueller

Objectives & Constraints

  • Objective: This challenge was to design and manufacture a holder for multiple sets of three 50 mL pH calibration tubes. This was to replace the old method of storing them in a beaker due to their conical shaped bottom.
  • Constraints: Must fit the tubes with minimal movement to avoid spillage. Must also have chemical resistance if spillage occurs.

Materials & Tools

  • Software: Autodesk Fusion
  • Materials: PLA and PC filament
  • Equipment: Bambu X1C 3D printer

Phases of Development

01
I. Modelling and Prototyping
  • The tubes were measured using calipers, and the holder was modelled in Fusion. Debossed text indicating which pH tube goes where were added. A prototype was printed in PLA for ufb01t testing.
02
III. Final Printing
  • Four models were printed on a Bambu X1C using transparent black PC filament.

Skills Developed

Text debossing in Fusion 360 3D printing with a difficult engineering material 3D printing tolerances

Support & Resources

  • Dr. Natalie Linklater
  • UNBC Hydrology Lab
