ND Filter Holder/Bumper for DJI Air Unit Cam

prusaprinters

I was looking for a way to mount ND Filters to my Air Unit Cam in order to get motion blur in my shots. Sadly I found only one (paid) solution which unfortunately left me with dark corners and didn't fit well in my frame anyway. So one led to another and after a few attempts I came up with this solution.It is meant to hold the original (or Chinese mockups) ND Filters that you can get for the Caddx peanut action cam. Those are quite handy and most important small enough to fit.To find the ND Filter just google “Caddx peanut ND Filter” and you should find plenty of sources.Here is a small example of what it looks like with ND 16 and bright daylight:  Unfortunately, the YouTube algorithm compresses the hell out of details, and/or I‘m just too stupid to make a proper video production. Also, the effect is not as pronounced as in a professional setup but at least I think it is an improvement in terms of speed perception.Since I like my things nice and organized I went the extra mile and designed also a carrying case as well as a dust protector cap.I am not too sure if the cap is a good idea because it might scratch the filter if debris got into it. But … well I already spend the time so here they are.Word of advice, I intentionally designed the ND Holder with pretty close tolerance to the actual lens to avoid unnecessary flares and/or distortion so please do not brute force the thing onto your cam or you might squash the TPU and scratch your cam or filter.PS: If you only need some protection for the camera u can just print one bumper and cap and you are set.Print SettingsPrinter Brand:AnycubicPrinter: VyperRafts:Doesn't MatterSupports: NoResolution:0,2Infill: 25%Filament: Eryone TPU and PLA Black Notes: Nozzle: 0.4mmTemp PLA: 190°CTemp TPU: 210°CBed Temp for both: 60°C (Like literary every print I am doing)Speed for both: 40 ish mm/s with 30mm/s for outer perimeter and top surfacesI had to adjust my retract to 3mm and 40mm/s for the TPU to not get tiny spaghetti all over the place.Overall I did not care too much about print/surface quality because I am crashing the damn thing anyway.For those who are wondering: The case is printed in PLA and the Bumper, as well as the cap, are printed in TPU.   Category: R/C Vehicles
