Making of Arri PL mount conversion adapter(PL-E, PL-MFT, PL-EF) & Front/Rear caps

I'm interested in Arri PL mount lenses when it comes to filming related to lens rehousing. Compared to the existing still camera interchangeable lenses, it seemed attractive to me that it was a relatively sturdy mounting structure, so it could be made stable enough even with 3D printing. (The steel camera mount is made of very small projections, so it is difficult to have a stable structure with materials other than metal) However, Arri PL mounts generally support the Super 35mm standard, but because of the very long flange back distance, PL mounts are not recommended for mounting/using vintage lenses for 35mm still cameras. Despite the advantages and disadvantages of 'PL mount' method mentioned earlier, 'PL mount' camera is not very common, so to mount a PL-mount lens to a popular Sony or Canon digital camera, you will need an appropriate conversion adapter for mounting. For the PL-E and PL-MTF conversion adapters, the difference between the flange back distance and the inner diameter of the camera-side mount is slightly different and almost the same. PL-EF (EOS) conversion adapter, short flange back distance (8mm), and narrow EF mount's inner diameter make the PL mount lens mountable very limited. Therefore, the PL-EF conversion adapter is not very useful because it is almost incompatible with the normal PL mount lens For the conversion adapter, it was modeled by slightly reducing (99.5%) relative to the X and Y axes of the rear part compared to the front part for smooth rotation. It is also designed 0.2 mm shorter than the exact flange back distance to cope with 3D printed output tolerances. Other parts - lens mount units(NEX, MTF, EF...) screw(1.5mm)
