3D PRINTED OIL FREE SHOCKER FOR RC CRAWLER, RC CAR|| CHEAP AND EFFICIENT || BUILT YOUR RC CRAWLER
These flat mounts are specifically designed for that purpose. This is the shocker cylinder and it is printed at six millimeter id. This is the piston rod of the shocker, and the washer of the piston head is friction fitted onto it. A washer with 2.9 millimeter id is printed and a three millimeter rod is inserted into it. You may notice a groove cut at the bottom portion of the piston rod. This is in order to facilitate the locking of the lower mount of the shocker onto the piston rod. The piston rod is inserted into the lower mount by aligning the groove with the hall of the lower mounts and a one millimeter nail is inserted to lock the rod. This is the damper for the lower mount. This will help the spring to be aligned in position for the easy and jerk free movement of the piston inside the piston cylinder. Okay, that’s all about the components now let’s move on to the assembly portion you may have noticed. The upper portion of the cylinder is kept open. This is because, once we fit the cylinder onto the chassis, the chassis frame will automatically lock the upper portion of the cylinder. This is how the piston rod goes inside the cylinder, a 0.2 millimeter buffer space is added inside. The cylinder that is the cylinder in inside is id of. The cylinder is printed with six millimeter diameter and the piston washer or the piston head is printed with 5.
8 millimeter diameter. The 0.2 millimeter diameter, the 0.2 millimeter buffer space, will ensure the smooth movement of the piston rod inside the cylinder. First of all, let’s lubricate, the inner side or the inner walls of the cylinder for the smooth functioning of the smooth movement of the piston rods, because the 3d printers print the components by layers. Others different layers are laid on each other. So the walls may not be smooth just like a injection, molded or plastic rods or plastic parts, as i have made an extension for the stabilizer of the rc shocker, we need to attach the spring or the insert the spring before, attaching it to the lower mount. So insert the spring first then align the rod with the hole of the lava mount then pressure the rod into the hole of the lower mount. So you can see the piston rod is inserted perfectly into the lower mount and the halls of the lower mount is kept vacant for locking with the help of the grooves cut on the rods. We can use a simple one, millimeter nail to lock the rod to the lower mount now let’s remove the excess portion of the nail with the help of a plier. You can see that the tension is not built inside the spring, so this is because the lower lock or the lower stabilizer damper of the lower mount is a to be placed. We can very easily insert this damper into position because there is a path cut for easy installation of the damper onto the rod.
Now you can see that the damper or the spring is placed perfectly on the inner walls of the damper and is lock the position for locking the upper end of the spring. There is a groove cut between the cylinder and the upper mount and it will go inside that group and get locked. So this is a very cheap and efficient design if you would like to print it or use this design. You can comment me on this video. I will send you the htl file onto your email id or i will upload the same on my google drive so that’s all for today.
