Description

1/18 Scale RC Toy Hauler & Boat Trailer – Printable Modular Kit for Scale Rigs

Build the ultimate tow-behind accessory for your scale crawler with this fully customizable, 3D-printable trailer.

Configure it as a boat trailer with guide posts, strip it down to a flatbed toy hauler, or set it up with tie-downs for hauling ATVs, bikes, or other scale cargo.

Designed to pair perfectly with popular 1/18 scale rigs like the TRX-4M, FCX24, and other crawlers.

Now Includes Split Frame for A1 Mini Printing!

Features

Modular Design – Switch between boat-trailer and toy-hauler configurations with removable guide posts and adjustable tie-down points.
True 1/18 Scale Fit – Sized for RC crawlers and compatible with our 1/18 scale PETG boats.
Tandem Axle Setup – Dual-axle design with realistic leaf spring suspension detail.
Strong & Rigid Frame – Prints in sections for easy assembly; rock-solid once built.
Trailer-Hitch Ready – Connects to standard 1/18 scale crawler hitches with functional tongue and jack stand.
Customizable Look – Print in your favorite colors, mix materials, or paint for extra realism.

Awesome! also check the profiles for the New Universal Hitch that is screw type!

@user_2099601675

Bit of a struggle to fit it on 2 a1 mini plates and some parts didn't print right (issue on my end) but I think once I assemble it me and my crawler freind will love it! Thanks for a great model

The designer has replied

@kadin_shino

oh!? what part? id like to make it as easly printable on the A1 mini as possible. Is it the longer side rails?

@user_2099601675

Replying to @kadin_shino :

the side rails just fit diagonally with little room to spare. what i meant is that it was challenging to cram all the parts onto 2 plates!

@kadin_shino

Replying to @user_2099601675 :

thanks, glad to know regardless!

@WeEatSandYum

A1 mini?

The designer has replied

@kadin_shino

Its going to take me a bit longer to figure out how to fit everything on the A1 mini unfortunately, but that is planned for the future! along with a slightly shorter boat and trailer to print without having to put to halves together!

@WeEatSandYum

I can also make a profile but I don’t know how to share it.

@kadin_shino

Replying to @WeEatSandYum :

Updated :) idk why i didnt build it like this to start lol way simpler then i thought.

@Adrian08

hey there, just a tip for the trailer, make the wheels have hexes that fit the trx4m tires so people can put the soft rubber tires on it. the hex for a trx4m is 4.15 or 4.1 mm, if you could do that would be great!!!!!!

The designer has replied

@kadin_shino

thats a great idea! ill update the print this week!

@Adrian08

Replying to @kadin_shino :

thank you!!!!!!!!!!!!

I’m trying to print with tpu on my a1 mini but I can’t figure out how to take the supports off without damaging it. any advice?

The designer has replied

@kadin_shino

I actually haven't had that issue yet....TPU is very annoying to print with. If not already, make sure tree support is set to slim. You can try running an exacto blade to cut the top supports off. Thats what i do. Also, probably in 3-4 days, i should have an update that changes the rim style and adds hex compatibility and some other things. i ment to get it out sooner but got distracted! But I keep seeing boosts, which is getting me to update this as a priority!

Looks so good on my fcx18!

@kadin_shino

New trailer model will be coming soon. This model will be moved to the boat profile because its designed specifically for the fishing boat currently built. The new trailer will be modular and customizable to build out to any size profile and axle count. So follow the boat profile to continue to get updates for this specific trailer! http://makerworld.com/en/models/1804565-1-18-scale-fishing-boat#profileId-1924603
