RC mattrax for 1/10, 1/12 scale with rubber tracks

thingiverse

Human: I designed and printed fully functional mattrax for my 1/10 scale and 1/12 scale RC cars at a fraction of the cost. These custom parts were specifically created for my WLtoys Chinese copy, model 12428. The vehicle is highly modified with a new base and tube frame. Only the rear and front axles are stock, but the tracks will fit standard 12428 models as well. BOM list for printing one track: Drivewheel - 1 piece Front wheelie - 2 pieces Wheelie small - 8 pieces Spine - 1 piece Wheelie link - 4 pieces Inner frame - 1 piece (mirror for the other side of the vehicle) Outer frame - 1 piece (mirror for the other side of the vehicle) The front travel limiter is suitable for model 12428, but the rear one may require a case-by-case assessment. Parts required: Rubber tracks - 4 pieces https://www.aliexpress.com/item/Remote-Control-Racing-Car-Tracked-Wheel-Tire-Front-Rear-Climbing-Off-road-DIY-Chassis-Tracker-for/32899304910.html?spm=a2g0s.9042311.0.0.27424c4ddEQLlO Central bearings - 8 pieces (17x23x4 mm, part number 6703ZZ) https://www.aliexpress.com/item/10pcs-6700ZZ-6701ZZ-6702ZZ-6703ZZ-6704ZZ-6705ZZ-Ultra-Thin-Wall-Metal-Shielded-Bearing-Ball-Bearings/32896374995.html?spm=a2g0s.9042311.0.0.27424c4ddEQLlO Wheel bearings - 40 pieces (3x6x2.5 mm, part number MR63ZZ) https://www.aliexpress.com/item/ZYS-precision-high-speed-spindle-bearings-708C-P4-HQ1-Ceramic-Balls-708-8mmX22mmX7mm-ABEC-7/32814152227.html?spm=a2g0s.9042311.0.0.27424c4d3q8apN Screws - M3x8, 32 pieces for small wheelies (I used countersunk head screws) M2.5x12, 32 pieces M2x8, 8 pieces for limiters Washers for the wheelie links to improve articulation - M2.5, 32 pieces
