YI 4K Adapter for 34mm filters

thingiverse

I use the Yi 4K on a multicopter and the best working ND8 filters available aren't those expensive ones you have to buy from drone stores. A very high-quality-demanding photographer believes that you can get an excellent glass ND filter for half the price in the photography sector. After printing, I lay the filter on the heated bed, screw it into the adapter, and let it cool down before using other filters. The thread is easily made. Note: I don't use the original lens due to excessive distortion, so I've adapted it according to my needs. You may need to make similar adjustments for your own multicopters. The SolidWorks file and STEP are available online, if you require any additional file types, just ask. For optimal results, print without supports, use a cooling fan, and set the layer thickness to 0.1mm or lower.
