Meyer Mini MkII – WRCCA Mini 1.9 Chassis

What This Is

If you’re after a competitive Mini 1.9 class rig that’s going to be durable and won’t break the bank, this is a solid option.

What’s Included

The zip file below contains:

  • Batt Tray 1.0.stl – print one
  • Body 1.0.stl – print two*, they’re your chassis sides
  • Electronics Tray Bed 1.0.stl – print one
  • Front Roof 0.5.stl – print one
  • LHS Chassis w rollbar 0.1.stl – or print *one of this instead and one Body 1.0.stl
  • LHS Rollbar 0.1.stl – optional, lets you later add a rollbar if you print 2x Body 1.0.stl
  • Rear Roof 0.1.stl – print one, or none – up to you
  • Skid 1.1.stl – print one
  • RC-TNT Meyer Mini Mk2.txt – the read-me.

Parts Needed

This is a bit of an advanced build. You’ll need to follow your nose for it. I’d suggest a 1/10 scale outrunner motor of no more than 14mm length, and ideally 12mm. You’ll also want 90mm shocks at most, and 80mm is probably best. A low-profile servo wouldn’t hurt, either. Keep the mass down as much as you can.

My Rig Used These:

MMMkII chassis side

How to Print

I printed in PETG, though other rigid filaments should be fine. I’d suggest these settings:

– 0.4mm nozzle (or bigger; I use 0.6mm)
– 0.24mm layer size (I used 0.3mm)
– 3 to 6 wall width (or wall or shell layers)
– 20% infill, cubic (10% minimum) – doesn’t really matter, it’s mostly walls
– No support needed.

Special thanks to Eric Meyer of Melbourne Comp Crawlers Inc. for his generosity and good sportsmanship in sharing his build approach and ideas with me. Eric’s design was a real influence on my approach to designing this one. Thanks Eric!

 

Thanks and enjoy this one!

Tow Hitch for Rlaarlo JK07

Tow Hitch Receiver for Rlaarlo JK07

What This Is

Rlaarlo hit it out of the park with the JK07. It’s brilliant. However, one thing it can’t do is tow a trailer. That ends today!

This is an easy print that will solve your towing problem, though you will still need the actual tow hitch itself.  (Does not fit TK07 without modification).

From Amazon: https://amzn.to/3FQa90k

Also will work: https://amzn.to/4jJF6B3

Rlaarlo TK07 & JK07

What’s Included

The zip file below contains:

  • Receiver.stl
  • Hitch Clip.stl
  • JK07 Hitch Bracket.stl
  • Read Me.txt

Hardware Needed

Tow Hitch Receiver for TK07

How to Print

I printed in PLA+, though PLA, PETG and other rigid filaments should be fine. I’d suggest these settings:

  • I print with a 0.6mm nozzle, but most of you reading this will use a 0.4mm nozzle.
  • I printed at 0.24mm, but 0.2mm will be fine as well.
  • Suggest 4 or 5 wall thickness
  • 25% Cubic infill for all parts.
  • I used PLA+. PLA should work fine, as should PETG.

Installation

  1. Open the body so you can access the rear of the car. It doesn’t have to be unbolted.
  2. Attach the Receiver to the JK07 Hitch Bracket piece with the 3x CSS screws. Don’t over-tighten!
  3. Remove the 8mm screws from the rear of the inner fenders. You won’t need these again.
  4. Align the JK07 Hitch Bracket piece between the inner fender holes. Loosely attach with 2x 12mm BH screws.
  5. Insert the remaining 4x 12mm BH screws into the Hitch Clip pieces and firmly affix these over the rails to the JK07 Hitch Bracket piece.
  6. Once you’re happy with orientation, tighten the BH screws with the rear fenders. Should be snug.
  7. Slide the tow hitch or drop hitch bar into the Receiver piece and insert a screw or two. Done!

Wheel Wells for RGT Intruder EX86020

(Last updated May 7, 2026)

What This Is

Wheel wells for the RGT Intruder EX86020. This is a gorgeous vehicle and it deserves the best!

RGT Intruder EX86020 Wheel Wells

What’s Included

The zip file below contains:

  • A printable STL file for each wheel well (4 total)
  • Read Me.txt
RGT Intruder EX86020 Wheel Wells Top

How to Print

I printed in PLA+, though PLA, PETG and other rigid filaments should be fine. I’d suggest these settings:

– 0.4mm nozzle (or bigger)
– 0.24mm layer size (I used 0.3mm with my 0.6mm nozzle)
– 3 to 6 wall width (or wall or shell layers)
– 20% infill, cubic (10% minimum) – doesn’t really matter, it’s all walls
– Supports on base only, 30% angle. Only need to support the flat parts where the wells ‘wings’ need support.

RGT Intruder EX86020 Wheel Wells Bottom

Installation

  • Print per the above settings.

  • Hold the wheel wells over the chassis to see where the screws need to come out.

  • Do one corner at a time; remove the screws from the matching holes.

  • Move the top of the shock to fit (I stood mine up; good for a scale car)

  • Align the wheel well where it’s supposed go and use screws that are 4mm longer than the stock ones (I think you need 4x 18mm screws and 4x 14mm screws, plus 4x 12mm screws and locknuts to suit for the top of the rear shock hoops if you want to add them too. Not critical).

  • Repeat for the other corners. It’s pretty intuitive; these should be plug and play.

Servo Bracket for Cross RC UT4 Pro

Servo Bracket for Cross RC UT4 Pro

Micro Servo Bracket for Cross RC UT4 Pro

What This Is

There’s a bracket on the Cross RC UT4 Pro that lets you have indepenent control of the front and rear diff locks with two servos, or to combine them and use just one servo for both.

However, a standard servo won’t fit, even with some cutting of the standard bracket. A micro servo won’t fit because it’s too small. The size that does fit is uncommon and you pretty much have to buy the Cross RC unit.

So, this bracket is one solution. to the problem. This bracket will allow you to fit a micro servo (like the Power HD TR4 or jxServo micro) to operate both diff locks at once, no cutting required. So much easier! Just be sure to use a strong servo!

From AsiaTees: jxServo HV1151MG

From Amazon: PowerHD TR4

Cross RC UT4 Pro Brackets

What’s Included

The zip file below contains:

  • RC-TNT Micro Servo Bracket for UT4 Pro.stl – 3D-printable STL file for the bracket to fit a micro servo;
  • Installing servo.jpg;
  • Print Orientation.jpg;
  • Read Me.txt
Bracket Print Orientation

How to Print

I printed in PLA+, though PLA, PETG and other rigid filaments should be fine. I’d suggest these settings:

– 0.4mm nozzle (or bigger)
– 0.24mm layer size (I used 0.3mm with my 0.6mm nozzle)
– 3 to 6 wall width (or wall or shell layers)
– 20% infill, cubic (10% minimum)
– Supports on base only, 7% angle. Only need to support the flat parts where the servo ‘wings’ mate to the bracket.

Installation

  • Print per the above settings.

  • Install servo into the bracket.

  • Place into the UT4 diff lock servo area.

  • Ensure you use the two extra triangular plastic mounts Cross RC supplies with the kit.

  • This bracket is designed to screw into those as well as the other end of the mount plate.

  • Continue with setup per manual for a single servo to do both diff locks at once.
