Baseplate set created using the Gridflock clips. 

It took me multiple tries to get the correct sizing and could not find the appropriate model on Makerworld so thought it would be usefull!

I can confirm the baseplate fits the Halfords Advanced 3 Drawer Chest, but do not have the other versions to check yet 

When assembling be carefull of any elephants foot (wider base of model) and if needed trim base of clips slightly to allow the pieces to fit together
