This is a saddle clamp to suit 21.5mm diameter pipe. With scaling it could be used for similar sizes (for example: scale 118% for 1" pipe, 102% for 22mm pipe, 93% for 20mm). The base is optional, and the top part could be used alone. At the original size, the overall width is 50mm, length is 35mm and height is 29mm.
The STL files should print easily without support in their original orientation. To test for a perfect fit at a particular scale, you could abort the print after the first few layers.
