MyRCCar 1/10 Shocks, Mostly 3D printable RC Car Shocks, from 55 to 110mm, including springs

myminifactory

Here you will find all the necessary parts to build a fully functional RC car shock, from the body to the spring, from the holders to the piston... covering a max hole-to-hole length range of 55 to 110mm in increments of 5mm. This publication is complete, with all bodies and springs included; I planned to offer these comprehensive sets at an affordable price, but I couldn't justify a subscription to the MMF Store as potential expenses might exceed revenue. Instead, I activated my PayPal account so you can now show your appreciation by tipping me if you like what I've done and want more! Remember, you can also support me with interest, likes, conversations, etc. Upon closer inspection, some parts require printing in TPU, such as the holders, "seals," and piston. This is necessary to run the shock with real shock oil or silicone. However, if you just want to try it out without oil, you can print the piston and top seal in PLA or PETG, while using TPU holders for added flexibility. As you can see from some photos, I'm currently using the smallest one (55mm) as a key-ring, similar to how I used 100mm ones in my pickup and now shorter ones on my on-road Tesla chassis. While they may wear out faster than sourced parts, they are very cheap to print and assemble. You can also use sourced components from bigbore shocks like O-rings or springs for added reliability. The same way, you can use these printed parts as a starting point and upgrade to more reliable components if needed. Now, let's get started on building it! All parts except the body and spring remain the same across all sizes. Choose between various "pistons" or "bigboreHolders"; I recommend using the 2hole piston and longer holders for optimal results. You can build a shock with a max hole-to-hole length of 55mm, as well as 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, and 110mm. The longer the shock, the greater its displacement range. For example, an 80mm from hole to hole shock requires a 3x40mm (3mm piano wire) shaft and a spring of 55mm length. In the most compressed position, this shock will have a max hole-to-hole measure of 55mm. Therefore, the SHAFT LENGTH must be HALF the max hole-to-hole for your shock, while the SPRING should be about 25mm shorter than the max hole-to-hole distance. Keep in mind that 3D printed springs have some memory when printed in PLA or PETG, so if you "pre-charge" them, their new spring length will become the normal length over time. To build reliable shocks, you'll need at least a minimum of 3mm piano wire, springs, and O-rings instead of the "bottom seal". If you're not too picky about quality, you can give these printed shocks a try! The cost per shock is significantly lower than sourced ones, coming in around $0.60 including plastic, piano wire, M3 screws, and o-rings, as well as the energy cost. If you can find cheap springs, you can have an even more functional shock for about $1.20
