Initially I bought some Samla boxes, but didn't like them, so after remixing another Samla holder to fit my needs, I needed a Sockerbit holder. Well, here it is.
The holder is a little longer, so you can either put the boxes on them with the cover lock tab on the long side or mount them fitting the short side like I did. They are removable in both configurations.
The author marked this model as their own original creation.
