Model information

CERN Open Hardware Licence Version 2 - Strongly Reciprocal

Print this for a replacement or customized knob for my dials and joysticks.

  • FDM allows for multi-material use, such as for the touch area.

    • needs 3× M3 heat inserts

    • to merge the touch ring with the body → select the same material

    • remember to change the type of the modifier to ‘modifier’ or ‘support blocker’ :-)

  • SLA has M3 threads printed-in-place, with an allowance of about 50µm

Print Recommendations

  • adaptive layer height

  • 3 walls or more if with a 0.4mm nozzle—conceptually the knob is a thicker vase

    • try different seam gap compensations (under ‘quality’)

    • enable ‘scarf seams’ for your filament

  • body: ASA

  • touch ring: PLA/wood, or something rubbery like TPU-for-AMS

  • The FDM version can be printed without any supports if you flip it on its head.
