This Spice rack is made to be mounted on the wall or on the back of the cupboard door.
This model provides the ends and the middle support section. you will need to get:
You can change the gap between the wall and the round support. The name of the parameter is “jarDiametre”. I recommend measuring the diameter of the jar and put an extra 1 or 2mm.
The height of the round support can also be modified. the parameter is “frontSupportHeight” and is measured from the top of the flat wood to the centre of the round support. Make sure it is high enough to hold the jars and doesn't cover the name of the spices.
