trailer designed to haul other 1/18 scale vehicles. I left the hitch open to use either a small jewelry eyelet or can be drilled larger and use a heim joint eyelet like the injora trailer. Uses 606 bearings for the wheel bearings. Everything glues together, some parts may require filing for fitment. Ramp brackets glue under the trailer, ramps store underneath. The random piece with 4 points is used to lock the ramps so they don't fall out(see pictures). uses standard 56mm tires, I doubt larger wheels will clear the fender. Assemble deck rails first, then install assembled wheel hub blocks into trailer deck assembly. Fenders glue in place after wheels are installed, as there's no centering marks for installing fenders. you should be able to assemble from the pictures provided. Its a work in progress, leave feedback and I can make adjustments.
upate: added an improved heim joint trailer tongue, uses small heim with 5mm diameter end, but will slide in using a bolt roughly 15mm length to secure. head is recessed into the tongue. 2 heim tongues depending on nut orientation to heim (see last picture)
fixed heim trailer tongue after some testing, and fixed fenders and hubs not lining up on print surface.
**easy heim joint to grab. snip the end off a stock plastic trx4m suspension link, drill the end with approx a 1.5mm drill bit then thread with spare bolt. (they use the trailer tongue imp pointed part)
Larger printers, download fenders and hubs, and whole trailer.
Smaller printers, download fenders and hubs, rails, ramps, trailer deck, tongue
