Measure with calipers:

• Inner diameter: Where the key goes (typically 7-9mm)
• Outer diameter: Body of the knob (typically 22-28mm)
• Height: How tall the knob is

Step 2: Get Nuki Interface Dimensions

The adapter must interface with the Nuki’s mounting socket. Download an existing adapter STEP file and measure the Nuki-side interface.

Step 3: CAD Software Options

Step 4: Test and Iterate

1. Print at 0.2mm layer height first (faster)
2. Test fit on cylinder
3. Adjust dimensions
4. Print final at 0.1mm layer height
5. Test with Nuki

Step 5: Share Your Design!

Upload to:

• Printables.com (recommended)
• Cults3D
• Thingiverse
• MakerWorld

Include:

• Photos of it installed
• Measurements
• Print settings
• Which cylinder brand it fits
