Parametric Wheel Spacers

Design of parametric wheel spacers.

Two types of wheel spacers.
Type A - used with thickness less than 10mm
Type B - used with thickness more than 10mm

Fully parametric. You can change:

• inner diameter
• outer diameter
• thickness
• number of bolts
• bolt pattern
• bolt diameter
• inner chamfer

Open file in the FreeCad program.
Double click on parameters.
Enter the desired measurements into the spreadsheet.

For example Alfa Romeo GTV 916 has wheels 5x98 with 58,1 center hole. So the measurements for 10 mm spacer would be:

• inner diameter - 58,1
• outer diameter - 138
• thickness - 10
• number of bolts - 5
• bolt pattern - 98
• bolt diameter - 12
• inner chamfer - 3

Plastic spacers are only for purpose to check your fitment. Never use plastic spacer on the road!!! Spacer must be made out of metal. You can export it for cnc machining.
