3D model description
I present the first set from the new Mini Monster Trucks series. These trucks are really tiny and can be printed really quickly (perfect if you want to make a small gift really fast). What's more, despite their size, they feature a fully functional dependent suspension system inspired by the Rocker-Bogie system.
The first set includes:
- Suspension system (in standard and 'loose fit' versions) and wheels.
- Two different monster truck bodies: a mini futuristic body (inspired by the Cybertruck*) and a pickup body (inspired by the old Ford F250* and Bigfoot*). Multicolor 3MF versions (created in Bambu Studio) of these bodies are included too! These bodies have been specially adapted for the smaller size, with adjusted proportions and a refined level of detail to suit their compact form.
- Additionally, a sinusoidal twist course is added to the set, as it is great for demonstrating the suspension system in action.
(For reference, it takes about 47 minutes (41 min + 6 min preparation time) and 11 grams of filament to print one of these trucks on the Bambu Lab P1S in standard mode.)
The assembly is very simple โ just attach 4 wheels and snap the body directly onto the suspension using a snap-fit connection, as demonstrated in the instructional GIF.
Be sure to check all the 3D Printing Settings information before printing!

3D printing settings
NO S!
- INFILL: 15% or more
- LAYER HEIGHT: 0.2 mm (or 0.1 mm for the Monster Truckโs body)
- NOZZLE DIAMETER: 0.4 mm
- MATERIAL: PLA, PETG
- PERIMETERS: 2 (recommended; more perimeters would only make the snap-fit connections stiffer)
The STL models are already in the correct orientation.
The prints shown were made on Bambu Lab P1S and Prusa MK4.
ATTENTION!
- The MMT_SUSPENSION_RB1.STL model is designed with 0.2 mm clearances between the walls of the print-in-place moving parts. Modern, properly calibrated 3D printers (tested on Prusa MK4 and Bambu Lab P1S) should handle this tolerance. However, if you encounter issues with parts fusing together in this model, an alternative fileโMMT_SUSPENSION_RB1_looser_fit.STLโis also included, featuring 0.3 mm clearance. To your printer's clearance tolerance, consider printing one of the many "Clearance Tolerance Tests" available online. If the parts still fuse together despite the 0.3 mm clearance, you may need to reduce the flow (extrusion multiplier) value or adjust the X/Y compensation (horizontal expansion) in your slicer (e.g., to -0.1 mm). Additionally, check whether the filament diameter is too large or if the nozzle is worn out.
- to clean the print bed before printing to ensure high adhesion.
- Once the MMT_SUSPENSION_RB1 is printed, rotate one side (axle) of the suspension clockwise and the other counterclockwise simultaneously. After a few rotations, the internal gear mechanism should work smoothly if it didn't initially.
