★★Please Read Carefully★★ This is a rear lens cap for Konica AR mount lenses, created from 3D modeling based on the mount shape. I'm offering this for those who want to use Konica lenses but are having trouble finding caps. This is intended for those who enjoy DIY projects and craftsmanship. Please refrain from bidding if you are overly concerned about minor imperfections, as this is a handmade item. 【Important Notes】 There are two requests: ① Scratches from Inspection Due to the nature of 3D printing, each cap is inspected for fit. Because we have repeatedly attached and checked them on actual lenses, there may be scratches on the inside. Please be aware of this beforehand. ② This is a Handmade Item After creation, we inspect the caps to minimize any excess material or imperfections, but please understand that this is a handmade item, not an industrial product. Regarding durability, please consider it as a typical 3D-printed handmade item. 【Cautions】 The design is such that it becomes tighter as you screw it on. Be careful not to force it, as this may cause it to loosen in the future. 【Background of Creation】 While Konica Hexanon AR lenses (Konica AR mount) are somewhat available, the number of genuine rear caps for Konica AR mount lenses is small, and third-party ones are not widely available, leading to high prices for used caps. I created this because I thought there might be people who wanted to use Konica lenses but were put off by the high cost of caps, or who were having trouble in practical use. Also, I hope that those who are considering selling their lenses but don't have caps can use these to protect the rear element. 【Additional Information】 BambuLab A1 mini (0.4mm) Made of PLA (Matte Black Filament) 3D model is self-made The printer was changed in November 2025, and the molding has improved. *Shipped via Yu-Packet Post Mini.
