This is an original jig for processing MS flexible chassis, made with a 3D printer. This design is from a Korean racer, and I am now offering it for sale with permission for licensing, etc. A thin-blade craft saw, such as those made by Tamiya, is recommended for processing, but any saw blade with a blade width of around 0.25mm can be used. The shape has been designed to make it easy to create clean cutting lines, even for those unfamiliar with the work. Also, unlike other products, it has a structure that can firmly hold the chassis, allowing for the production of accurate flex. There may be layer lines characteristic of 3D printers, but this does not affect use. In addition to this product, a saw, nippers, etc. are required for production. Please use with sufficient attention to safety. I will carefully explain how to use it until the end, so thank you. license Designed by kosuyoung pro. Thanks to your good designs.
