*Keep in mind 3D printed parts will have texture. Think of them like model car parts. May need a light sanding, A xacto knife trimming small supports or paint if you wish. Usually 1 side was attached to the printer bed and it may be the roughest. Lightly sand and usually fine. Thanks again for your interest. Description: 4 Discs that snap into the fat Stomper tires so they will work on Stomper II Track Systems. These are typically missing so these help get them back working on Stomper sets. Colors available pm me *Will not fit skinny tires **Stomper vehicle not included 3D printed plastic parts can break if you get too rough with them but I've had mine on and off a dozen times wirhout failure. Do not use tools such as screw drivers to pry them out. It will arrive unbroken. No warranty beyond that ~When you receive your 3D printed Parts they may have a small amount of Elmer's Glue on the back wash with warm water for use. *No trucks or other parts included! Please be careful removing your old tires as Stomper rims get brittle in time. I'll post a how to video on the Stomper Museum soon to help. Please zoom in for further conditions. Looks nice otherwise. Condition is Used. Shipped with USPS First Class Package. We ship within 24 hours of receiving payment unless a holiday or the week ends. We upload tracking to the listing Pay Pal. Since we are in the Mid West expect longer transit times to the coasts. Please do not grade us upon the United States post office transit times we have zero control over that. If the tracking shows it was picked up in Eldorado, Illinois the day after you paid then we shipped fast for you. Our local mail hub is now in Missouri once it leaves Eldorado. This ads a day or two to the transit times if you are ion the west coast. Please be patient we are doing all we can to speed things up. Disclaimer: We make these in the best 3D materials we can find but they are still small fragile plastics. If you attempt to hammer them or drive them onto the axles they will break. We leave a 2mm hole on the bottom that you can enlarge with an x-acto knife until they slide on. If you take your time use common sense these will bring you a long term replacement. I also have a video on installing and removing Stomper tires on The Stomper Museum. It will make things much easier for you and save you the costs of buying more! Not responsible for accidents. Wear safety goggles or a helmet if you need to! Thank you!
