Made with a 3D printer. This is a jig that can be used as a template when processing the catcher for the MS chassis catcher damper, a standard modification for Mini 4WD cars. The product includes only the first image; the second image of the car body is not included. The thickness is 2mm. The hole positions are the MS chassis hole positions at the front (photo 2), and holes that fit the three-hole and two-hole mass damper squares at the rear. The hole diameter is 2mm. The rear sides are carved out with 30mm diameter semicircles, so you can use them as is, or you can ignore the guide and cut straight, then process them to fit. Also, due to the nature of 3D printing, there may be warping, burrs, stringing, and chipping in fine details. We only sell and ship items that do not have any problems with use, but please understand that the above details cannot be avoided. Thank you. #Mini4WD #TAMIYA #CatcherDamper #Jig #Oni-chan's Type...Mini 4WD Specifications...Other Scale...Other
