★★Please Read Carefully★★ This is a self-made rear lens cap for TAMRON Adaptall 2 lenses, created using 3D modeling based on the mount shape. This cap is designed to protect the lens when an Adaptall 2 adapter is *not* attached, so please be careful not to misunderstand. I'm offering this for those who use TAMRON Adaptall 2 lenses. This is intended for those who enjoy DIY and crafting. 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, we will send them with scratches on the tabs. Please understand this beforehand. ② This is a Handmade Item After creation, we inspect the caps to minimize any excess material or burrs, 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 Adaptall 2 structure is complex, so the cap is designed to fit tightly after a certain amount of turning, and it will come off if you continue to turn it. 【Background of Creation】 Recently, the Adaptall 2 mounts themselves have become expensive, so I made this for those who are reusing a single mount. (I am one of them) By the way, the original is reportedly made of transparent plastic and is rarely available. I created this because I thought there might be people who are using TAMRON lenses from the Adaptall 2 era but have more lenses than Adaptall mounts, or are having trouble in practical use because they can't get the required number of mounts. Also, for those who are thinking of selling their lenses but want to keep the Adaptall mount, I hope you can use this to protect the rear element. 【Additional Information】 Anker Make M5C (0.4mm) Made of PLA (Matte Black Filament) 3D model is self-made *Shipped via Yu-Packet Post Mini.
