ZMR250 Arm longer with different hole spacing and different motor mount

thingiverse

Because different hole spacing in circulation I have uploaded the four most common measurements for installation. The total length is 123mm and six-inch props can be installed with ease. The length from motor mount middle to first frame mount hole middle is precisely 86mm. Additionally, this version includes two distinct motor mounting dimensions. You can clearly see in the picture which measurement corresponds to A and which to B (frame mount dimensions are M3). Please note that the filename requires a comma; 125 should be written as 12.5 for accuracy. Motor Mount Dimensions: * 11.8mm - 16.2mm, M2, suitable for models 1804 and 1806 * 15.8mm - 19.2mm, M3, ideal for models 2204 and 2206 Inner Hole Dimension: * 6.5mm, compatible with models 1804 and 1806 * 9.0mm, suitable for models 2204 and 2206 Please note that these measurements are not intended for 3D printing but rather for CNC applications, specifically with normal 3mm carbon materials. You can send the relevant file to an appropriate company, and they will provide you with the correct part. My preferred choice in Germany is actually https://noblish.com.
