We have created a product that is affordable and allows beginners and those who want to easily try MS Flex to build it properly. Although it may be inferior to slightly more expensive products, we have paid close attention to the materials and layering. Regarding the price, it is low because we have reduced our profit margin. This is an original jig for processing MS Flex chassis, made with a 3D printer. This is a design by a Korean racer, and we are now able to sell it because we have obtained the necessary licenses and permissions. For processing, a thin-blade craft saw, such as those made by Tamiya, is recommended, 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 creation of accurate flex. There may be layer marks unique to 3D printers, but this does not affect the use. In addition to this product, a saw, nippers, etc. are required for production. Please use with sufficient attention to safety. If you need instructions on how to build it, please let us know in the transaction comments. We will carefully explain how to use it until the end, so thank you for your cooperation. license Designed by kosuyoung pro. Thanks to your good designs.
