Made with a 3D printer. This is a jig that can be used as a template when processing the catcher for the catcher damper for the MS chassis, a standard modification for Mini 4WD cars. The product includes only the first image; the car body in the second image is not included. The thickness is 2mm. The hole positions are the MS chassis hole positions in the front (as shown in the second photo), and holes that fit the three-hole and two-hole mass damper squares in the rear. The hole diameter is 2mm. The rear sides are cut out with 30mm diameter semicircles, so you can use them as is, or you can ignore the guide and cut straight, then adjust to the actual product. Also, due to the nature of 3D printing, there may be slight warping, burrs, stringing, and chipping. 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.
