This is an original jig for processing MS flexible chassis, produced with a 3D printer. This design is from a Korean racer, and we are 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 firmly holds the chassis, allowing for the production of accurate flexible chassis. 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. We will carefully explain how to use it until the end, so thank you for your cooperation. license Designed by kosuyoung pro.
