125mm Deep Modular Shelf

I couldn't find a shelf that quite met my needs, either size or design. So I designed this. The shelf is 125mm deep and 280mm long (5mm at each end slots into the bracket giving usable length of 270mm). There is a 5mm high lip at the front to stop things rolling off. Unlimited length can be achieved by using multiple shelves and the middle bracket. If anyone would like other shelf lengths then please let me know and I will try to get an updated model added. All parts were printed at 0.2mm layer height in PLA. Added additional shelf sizes.
