I needed to raise a desk 100mm for my wife to work comfortably from home during this Covid pandemic.

This is my first Thingiverse 'offering' so be kind.

I've uploaded the STL and also the Fusion 360 file incase it's of any use.

The height overall is 130mm to take a table leg to 40mm x 50mm with 30mm depth of the leg inside the part.

Hope it's useful to somebody.
