Metal Brackets
The plastics for the bookcase, telephone and bearkick ramp are attached with metal angle pieces to their corresponding plastic supports. So I will have to acquire these brackets also if I don’t want to use the old ones, which I don’t.
A few enquiries on RGP and flippermarkt.de revealed nothing other than a recommendation to get such angle pieces from the local hardware store. So I went looking.
I found two potential solutions: angle strips one out of aluminium and one out of plastic, which I could cut. As they didn’t have my required size (15mm x 15mm) in aluminium, I opted for the hard plastic version.
