WPL C14 Side Fuel Tank for Li-Ion 18650

thingiverse

Well so the WPL 1/16 C14 is a rock crawler at heart, given its low speed and grippy tires. However, its center of gravity (CG) is unfortunately too high. The goal here was to design a lookalike fuel tank that houses two 18650 Li-ion batteries inside. It's mounted directly in the middle of the chassis, significantly lowering the CG compared to the original location, thereby reducing the risk of tip-over during steep climbs. To achieve this, I used my 3D printer with the following print settings: a. The side fuel tank V2 should be printed at a layer height of 0.3mm, oriented upright for the best possible finish. A brim and support are also recommended. b. The clamp 1 & 2 must be printed at a layer height of 0.1mm. A brim is absolutely necessary in this case. c. For the cover + & - V3, I tried printing it at 0.1mm with the symbol facing upwards. Assembly involves drilling the fuel tank mounting point with a 2.5mm drill bit and then securing it to the chassis using an M3 screw. Next, glue the clamp onto the tube. Once you've wired up the two Li-Ion batteries, cover them up with the cover + & - file.
