The model has two variants:

• SINGLE PART - the rim is printed all at once
  • many supports,
  • no assembly needed
  • low accuracy of the axle hole
• 2 PART - the rim is divided into top and bottom part (shown on photos)
  • assembly with supergule or gluegun needed
  • less supports
  • can use ugly filament for the bottom part
  • axle hole printed directly on bed - better accuracy and fit OK to original Technic axles
  • if printed from STEP file, need to be divided into objects manually
