knob for dials and controller

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.
