DJI OM 5 Shotgun Mic Mount

DJI OM 5 Shotgun Microphone MountThis is a simple design to mount a 22mm diameter shotgun mic to a DJI OM 5 gimbal. I'm using the phenomenal Comica CVM-VM20 however, this should theoretically work for any mic with a diameter of 22mm like the Comica. The mount uses the small M3x0.5 screw hole meant for mounting counterweights. Do note the design is meant for an M3x12mm Screw and won't work with anything else as the threaded hole is only ~3mm deep. MK1.1: Added an M3 threaded hole to the center of the model to store the M3x12 screw when not in use.With that being said I DO NOT recommend using this setup or trying to mount an external shotgun mic to the OM5 as it can't support the weight properly. I did use this with a phone that weighed 230g and with the microphone and mount at about ~100g, which comes out to 40g over the max gimbal supported weight of 290g. However, with that weight, the gimbal was barely operating and it induced wobble even in completely stable & unmoving positions requiring me to slightly stabilize all my footage in post. Occasionally the gimbal would even get into these resonant wobbles that made the video almost entirely unusable. If you can manage to keep the payload weight below ~310g with a small phone, this might work alright, but the performance of the gimbal will be hindered no matter what due to the increased moment of inertia.NOTE: I designed this in about an hour as I was in quite the rush so please forgive the poor design and terrible F360 layout as I just needed something ASAP. That being said, it did work on the first print :)DJI OM 5 3D Model: https://www.thingiverse.com/thing:5155717I'd recommend using this design instead as this doesn't add any weight to the gimbal phone mount, https://www.thingiverse.com/thing:3859901 Print SettingsInfill:~30-40%Filament:Polymaker PolyLite PLA Pro GreyNotes:I'd recommend printing this at an infill of ~30-40% as anything higher than that will probably result in the print cracking when fitting the microphone. Printed with 3 perimeters and 3 top & bottom layers. You may also want to do a height range modifier to print the screw mounting section at a higher infill for increased strength.
