About this 3D model

This time let me start with the most famous song from Bob Dylan: "How many times must a man re-designBefore you call it a "must have"?How many roads must a chassis withstandBefore you upload it online? The answer, my friend, is MyRCCar KIDSThe answer is MyRCCar KIDS" FEATURES: - Simpler and stronger chassis with configurable wheelbase from 250mm to 300mm in steps of 5mm - Configurable caster per axle in different positions - With this new design, you will only need some allen or screwdrivers to change these features, instead of having to print and change some parts - Most of the edges has been softened so it is less lesive for kids in the worse scenarios. The same way, the gearing and central transmission has been covered to avoid kids contact New 3d printable 1/10 RC car drifting / on-road / touring / rally chassis redesigned with exclusive features as adjustable wheelbase or rotating axles to adjust caster.Instead of having to re-print different parts you will just need to un-screw a few parts and screw them together again in a different position. Adjustable wheelbase: The idea behind this is to be able to use different wheelbase bodies without having to reprint parts or a new chassis. The car is mainly divided in two big parts, the front and the rear, which can be screwed one to each other in different positions.This allow you to choose your prefered wheelbase from 250 to 300mm in steps of 5mm, which shoud be fine for most of on-road cars. The best thing about this feature is you don't need to disassemble any electronics or mechanic parts, as they are fixed to the front or the rear part but not both.Another great thing about this is you don't have to adjust the central transmission length for each wheelbase as it is also designed "elongable" to acomplish the "adjustable wheelbase" feature. Adjustable caster: The same way than with wheelbase, the idea is to be able to choose from different caster angles for your Front and Rear axles without having to re-print parts to acomplish it.I have tryed to re-imagine the suspension system and now all those parts (arms, arm holders, butterfly and butterfly holder) are linked to some new parts which I call F/R Diff Box Sides!. These sides rotates over the real diff. box and are conected to each other with the butterfly and the front lower arm holder.When correctly assembled the whole front or rear axle (including the transmission, steering links etc) can rotate a few degrees to the front or the rear. Once you have chosen your desired caster for each axle, you can use one screw on each side of the axle to fix the caster position. These screws go through the diff box sides using different holes and screws in different holes in the main F/R diff boxes. Choosing the right hole can be kind of a game itself :S Other features: - Direct Motor Pinion / Crown or geared main transmission - Low profile - Light weight - Number of parts and screws reduced compared to other models - Support free*, most of the parts don't need supports - Great steering angle (near 45º) - Great and quite protected space for battery (140-190mm long, 50mm wide, 25mm high) - Holes for what is coming What is included? This publication is about the chassis. You can see various bodies over the chassis as a demonstration of its capabilities. The same way, you can see 3D printed wheels and shocks which are not included. The blue and red Tesla Roadster 2020 are 260mm and 275mm wheelbase versions in PetG and TPU respectively from the great Roadster design from Shadowcraft Designs - Main Chassis, Steering, Suspension, Transmission, Body Holders and Bumper parts are included - "MRCC_KIDS_TESTPART" to test your printer and selected slicing process before printing big parts - "MRCC_KIDS_template_80mm_holes" Simple template "tool" to help marking holes in the body - "Fake Axles/Pins" to be 3D printed while you can source the metal ones - Motor pinion for the standard "geared" configuration. 2 versions of a 14T Mod1 Motor pinion, for 3.17mm and 5mm motor shafts - Simple bad-english writen assembly instructions attached, indicating screw type and size for each step, naming and identificating parts Materials: As PLA has been the cheapest material during a while I have designed and printed my designs with it. I think if it works with PLA, it should work even better with other more "industrial" materials as ABS or PETg. Personally, I never took control completely of ABS printing, and I'm actually experimenting with PETg. What I mean is that sometimes can be better a good print with a bad (PLA) material than a bad print with a good (and more expensive) material. So a very good inter-layer adhesion will help making the mechanical behavour of your parts more omnidirectional. Can you do that with PLA?¿? If you do, remember not expose the chassis in the sun and heat for hours and monitor and control temp of your motor and electronics if you don't want surprises. ODE TO TPU:The same way I think PLA is enough for most of the p
