ZMR250 Arm with Motor Protection shorter longer and normal with different hole spacing only for 22xx Motors

thingiverse

This are my new interpretation of ZMR Arms with\nMotor protection\nAnd its stronger (look at the pictures)\nIn one of the pictures you can see two circles. The inner circle (27mm) is like an 22xx motor and the outer circle (33mm) is to demonstrate how much space is to the motor protection.\nBecause different hole spacing in circulation I have even uploaded the four most common.\nThe total length is 123mm, 117mm or 105mm. The length from motor mount middle to first frame mount hole middle is 86mm, 80mm or 68mm. And in this versions there are only one motor mounting dimensions.\n-The shorter version is intended for only 5 inches propeller\n-The mean length, also standard version, is like standard arms and on a standard ZMR normally you can mount 6 inches propellers\n-The longer version is intended for special ZMR buildings like an chopped ZMR. With this length you have no problems in any situation with 6 inch propellers\nYou can see in the picture which is A and which is B (frame mount dimensions M3) (in the Filename is missing a comma, 12 5 is 12.5...)\nMotor mount dimensions:\n15.8mm - 19.2mm M3 (2204 2206 motors)\nInner hole dimension:\n9.0mm (2204 2206 motors) \nNot for 3D printing but for CNC (normally 3mm carbon)\nYou can send an appropriate company and then get the right part.
