Made by SIG.WORKS Processing jig for MS Flex chassis Cutting guide for angled cuts and flat cuts. A unit slicer is also included as a bonus. (The unit slicer has been repaired with instant glue, but it is a 3D-printed product, so it may come off if force is applied. Therefore, it is offered as a bonus.) I used it when creating an MS Flex chassis for Mini 4WD, but I may not have used it more than 5 times.
