Traxxas X-Maxx CVD boot adapters

thingiverse

These are the adapters that allow you to put CVD boots available for HPI Baja on X-Maxx. Then you can grease the CVDs and stop wearing them like crazy. It also looks freakin good and holds up to the abuse well. UPD2: Been testing them for 20-30 packs. All are ok except one which I assembled incorrectly and it slid off the CVD cup. Got torn instantly while hanging loose there. UPD3: Added retainer for attaching boots to stub axles. You'll need twelve M2.5x5 screws, 2mm drill bit and m2.5 tap. Use the screws with smallest head you can find. Make sure you don't drill the holes too far from edge, i.e. too close to wheel side. This will make the retainer rub on bearing. Dry test the fit before drilling. Drill the holes after you cut and glue the axle boot. Just put the retainer in place and drill through one hole in it. Tap it, put screw in it, then do the rest. Obviously the boots that go over stub axles need to be cut a bit and glued to retainers. You can see it in the photo. Again, dry test the fit. Don't cut too much boot, leave ~3mm edge as measured on the inside or ~5mm on the outside. Otherwise it won't fit and you'll need a new boot. You'll need to cut some plastic off stock axle carriers to make space for retainer. If you have RPM on rear then you only need to do this on front. Big part that should be glued to the drive cup has never been printed, I have it done differently on mine using some aluminium pipe (lots of work). You need to print 4 of those small parts per axle, then glue them in pairs over the axle to each other but not the metal. Then pull the boots over them. Also, Loctite or super glue the Traxxas CVD pin to aluminum stub axle. This will stop the wear since it will pivot around steel to steel, not steel to aluminum joint. And it will stop grease from escaping through the gap there. There's a small part, CVD axle grease plug. It's optional and is used to plug the inside of axle boot. There's a big empty area there and grease will escape there instead of lubricating the joint. Just push it in far enough to make sure the dogbone doesn't rub against it.
