Cults3D
This model allows you to increase the height of average shelf by utilising original hole, but lifting the shelf platform.
There are 3 models here , 25mm, 35mm and 57mm.
This model is what allowed me to store books upright where before they would not fit, or to lift liquor cabinet shelf so tall bottles can fit inside.
If you need different height feel free to shoot me message and I can upload an addition.
