Portable 3D Printing Refit Mini Version Rainbow Polaroid SK1

In 2016,I modified a Polaroid mini camera (prototype) with a folded-back structure was transformed by using the interior of the Polaroid Rainbow Machine. It has a small size, a palm-sized body, a compact overall feel, and is very portable. Although the focus is estimated, but the playability is strong.

Some like it, so I used the free time recently to model the engineering 3D file from the new design. I used LOMO's mini film back and a cost-effective Konica Pearl II 645 camera to create a new one. The mini Polaroid was named SK1.

It has been revised and improved before and after, and various versions have been tested. The final shape is still small and portable. In particular, here is the Konica Pearl II 645/120 camera. The lens assembly itself is more advanced for the whole group. The lens has a convenient focus knob. The lens is Konica's own hexar75 / 3.5. , The imaging quality is very good, the shutter speed is very complete and very powerful B \ 1 \ 2 \ 5 \ 10 \ 25 \ 50 \ 100 \ 250 \ 500, including the shutter line socket, the machine is cheaper in the second-hand market, it is very suitable for use Makeover. When remodeling, just remove its lens. Of course, other lens shutter groups can also be used, but you must try it yourself.

The design of the fuselage 3D engineering file takes into account the characteristics of ordinary FDM melt-extrusion 3D printers, and breaks it into upper and lower parts to improve the printing success rate. It is recommended to use ABS / or industrial fiber / nylon, etc. Higher melting materials,

This SK1mini Polaroid can currently shoot focal lengths in the range of 0.5-1.5 meters, suitable for portraits and sketches, and the shutter is fully manual. The project file will be provided for Baidu web disk download. If you want to build a similar structure, portable return The Polaroid mini camera can be downloaded and assembled by yourself. The following will use the installation instructions with emoticons (this simple camera is not perfect, there are still many problems that need to be improved, and you need some patience and hands-on ability, any feedback and comments are welcome)

The fuselage engineering print file is currently divided into five parts as follows: BODY_down BODY_up Cold boots Reflective lens cutting, refer to the plan view, thickness less than 2mm Print viewfinder (rough range) can also be mounted on other 75 focal length viewfinders of other 120 rangefinder 645 cameras

As far as fun is concerned, making the machine small might not be a good choice. Just as the original idea of Olympus's genius designer Yoshihisa Maitani provided the world with unique compact and exquisite PEN and OM film cameras. Today, even digital, PEN's digital cameras are still alive. Not to mention that there is no need to enlarge the film of the instant camera.

I look forward to seeing everyone build their own unique Polaroid mini

便携3D打印改装重造mini版本的彩虹拍立得机SK1

2016年的时候，曾利用宝丽来彩虹机的内胆改造过一台折返结构的拍立得mini相机（原型机），体积小巧，巴掌大小，整体手感紧凑，非常便携。虽然估焦，但可玩性较强。

很多朋友看了颇为感兴趣，于是近期利用空闲时间，从新设计建模了工程3D文件，用LOMO的mini吐片后背和一台性价比很高的柯尼卡 Pearl II 645相机从新打造一这台命名为SK1的mini拍立得。

前后不断修正完善，测试了多种版本，最终外形还是以体积小便携为本。特别在此说明一下，柯尼卡Pearl II这台645/120相机，其镜头组件本身为整组移动较为高级，镜头上有很方便的调焦旋钮，镜头是柯尼卡本厂的hexar75/3.5，成像素质非常不错，快门速度很完整很给力B\1\2\5\10\25\50\100\250\500,含有快门线插口，机器在二手市场上价格较便宜，很适合用做改造。改造的时候，只需要拆下其镜头即可。当然也可以使用其他的镜头快门组，但具体要自行尝试。

机身3D工程文件在设计时考虑到普通FDM熔融挤压式的3D打印机的特点，将其分解为上下两个部分，提高打印成功率，建议使用ABS/或者工业纤维/尼龙等较为结实坚硬，熔点较高的材料，

这台SK1mini拍立得，目前可以拍摄0.5-1.5米范围内焦段行程，适合人像和小品，快门全手动，本次工程文件将提供百度网盘下载，如果想要建造一台类似结构，便携折返拍立得mini相机可以自行下载组装，以下会以图释使用安装说明（这台简易相机并不完美，还有很多问题需要完善，需要你有一定耐心和动手能力，欢迎任何反馈及留言）

机身工程打印文件目前分为5个部分如下： BODY_down BODY_up 冷靴 反射镜片切割，参照平面图，厚度2mm以内 打印取景器（范围粗略）也可自行安装其他120旁轴645相机的75焦段取景器

就趣味而言，把机器做小未尝不是一种很好的选择，正如奥林巴斯的天才设计师米谷美久Yoshihisa Maitani一开始所持的理念，为世界提供了独特小巧精美的PEN和OM胶片相机，乃至数码化的今天，PEN的数码相机仍然健在。更何况不必放大底片的即显即影相机。

期望看到大家自行组装别具特色的拍立得mini
