You just need to print the clips and you can use the stands that come with the cupboard to fasten the clips onto the furniture piece. As you fasten the clips, they should grip the Dremel rod.
If you don't have the stands, any fastener that fits into the cupboard can be used instead.
You won't need support if you print the clips on the side.
I've included the stp files in case you want to modify them.
