ND Filter Holder/Bumper for DJI Air Unit Cam

thingiverse

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. The actual ND Filter Set I am using can be found here: https://de.aliexpress.com/item/1005003478416192.html?spm=a2g0o.productlist.0.0.1f254a3cECTYuA&algo_pvid=e9be9505-85fd-4dfe-ab00-fc8655696193&algo_exp_id=e9be9505-85fd-4dfe-ab00-fc8655696193-52&pdp_ext_f=%7B"sku_id"%3A"12000025967573748"%7D&pdp_npi=2%40dis%21EUR%21%218.75%21%21%214.69%21%21%4021031a5516572013545608620e92f9%2112000025967573748%21sea (Of course, it's AliExpress because I am a cheap bastard :P ) Here is a small example of what it looks like with ND 16 and bright daylight: https://www.youtube.com/watch?v=L6v7ngweJ2Y 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. One more thing, after writing all this bull**** fumbling with picture sizes reuploading everything several times, and FINALLY hitting the publish button... It told me to upload at least one file in formats like STL or OBJ (Which I did afterward:D) ... Well but I am using 3mf in my workflow and as long as nobody complains you are forced to do so too :P. But don't be afraid my friend 3mf is as simple to use as STL. PS: If you only need some protection for the camera u can just print one bumper and cap and you are set.
