1:10 scale offroad utility trailer (mesh sides) for rc crawler

thingiverse

This is a Utility trailer for 1/10 scale RC Crawler cars, based on FarmersMark's Design (see source). I redesigned most of the parts, but all credits to Mark for the idea. What you need: M3 screws and nuts; I lost count unfortunately. But if you build crawlers and rc cars, you should have plenty anyway. 2x aluminum channel (u-profile): 12mmx12mm outside, 8mmx10mm inside, 2mm thick, length: 195mm 1x 3mm thick baseplate, 210mm x 180mm 4x Ball bearings, 5x11x4 (Tamiya DT-03 has those for example) 2x Traxxas Axles, TRX3637 2x Traxxas Wheel Hubs, TRX3654 (or any other that fit, doesn't really matter) I used some chipboard as baseplate, but any 3mm plastic plate will do. You could even print the aluminum channels if you can't get those, I took those because I had them lying around and to strenghten the chassis. For heavy loads, I suggest reinforcing the leaf springs as I broke one already. How to build: Well, print everything. If you need a part multiple times, it is named "_make2" or "_make4" in the filename. I used TPU for the spring mounts in the back and mostly PETG for all other parts. The mesh is printed with PLA, mostly because I had no black PETG. The Frames on the side have a slot for the mesh part, be careful with support structure or you'll curse for hours while cutting it out. The front spring mount has 3 versions. I used the V2 in PETG, it has smaller holes so you don't need a nut on the outside. This won't hold very long in TPU, though, so take the normal versions with that. After printing, build the chassis first, then mount the baseplate on top with some screws. After that, add the 4 frame-parts (with mesh inside) and screw it together with the 4 connectors on top. The trailer hitch mount is designed for a MST CFX-W. More pictures and a little build log (in german) here: https://www.rc-modellbau-portal.de/index.php?threads/kasis-mst-cfx-w-jp1.7161/page-4
