You are looking at a 3d printed OO Gauge Model Railway Sloping Wall - available in 1,2,3, 4 or 5 pieces.
This set of designs are for a sloped section of wall that is ideal for a road or something similar. They come in several sections that work up to the 100mm or 120mm heights. The designs are in left and right hand slopes so please select which option you would like from the drop downs as this does effect the detail on the pieces (more detail on the front facing side hence requiring an orientation selection).
Dimensions:
The walls are 9mm deep and the pillars are 15mm deep and about 12mm wide. each section is about 126mm long. The angle of the slope is 9 degrees.
Its quite hard to show proper dimensions below as the walls are obviously sloped but please ask if you need any further measurements. Heights are the tallest points on the pieces - top of the end pillar, but useful measurements if you want to achieve a certain height to join on to something else.
1 Piece: 138mm Long (longer than the other pieces as it has the end pillar) x 45mm max Height
2 Piece: 264mm Long x 65mm max Height
3 Piece: 390mm Long x 85mm max Height
4 Piece: 516mm Long x 105mm max Height
5 Piece: 642mm Long x 125mm max Height
