Before you start

  • Get ready all tools.
  • Buy necessary parts that cannot be printed (screws, bearings, motor etc.), these parts are listed on next page.
  • Make sure that your printer is calibrated well – print our “calibration part” to ensure that you can fit bearings on shafts properly! Calibration part is located on “Print 0 - Calibration”.
  • Use higher printing temperatures – use about 210-215°C for PLA to have firm layer adhesion!
  • Use some heat-resistant filament (PC Blend) for specific drivetrain parts noted later in this Guide!

  • Build guide is divided on steps and subassemblies. Subassembly is a sequence, where you will make some independent sub-part like gearbox, axles etc. Later you will install subassembly in the car.

  • Bamboo 4x4 Pickup includes 2 different wheel designs. Both designs shares the same tire dimension, so feel free to choose the right design for you:

  • For “Wheel C”, print plates with “Wheel C” in name.

  • For “Wheel H”, print plates with “Wheel H” in name.

Are you new to the Radio Controlled models?

Don’t worry, Radio Controlled (RC) models are not as complicated as they can look! However, it’s a good to know some basics before you will start buying parts.

Most mechanical parts in our products will be 3d printed on your own printer, so we will focus here on RC electronics.

On-line beginners guides:

If you have any questions regarding our models, feel free to ask us (or other 3D Sets

builders) on our Facebook discussion group, available here: Facebook – 3D Sets

BeltDrive 4x4 Gearbox – introduction

71

BeltDrive 4x4 Gearbox uses 4 identical timing belts – HTD 144-3M-06 (HTD profile, 144 mm long, 3 mm teeth distance, 6 mm wide).

BeltDrive 4x4 Gearbox is compatible with all 4x4 3D Sets models, so you can use it in your older Rancher/Landy without any modifications.. With this gearbox model is moving faster and has more power. Gearbox is very silent and reliable when assembled properly. Gearbox work with brushless outrunner 750-1000 kV and 2S-3S battery

Please check motor temperature by hand if you are driving in rough terrain or for long periods! If you are using model in hot weather, please print gearbox case (enclosure) from PET-G or other heat resistant material.

Internal belts/pulley configuration is shown below:

72 of 155

Important features

72

Bearings calibration

It is very important to check if small 3d printed shaft ends fit the bearings properly, because such small printed objects may shrink too much.

There are two sizes of the “Pulley Shaft small” parts (located on print “Belt Drive Gearbox - 2”):

S” = standard size; “L = larger size

Please try if the “S” sized part fits the bearing without any gap. The bearing must hold on place firmly, otherwise, the gearbox can be damaged! If there is any gap between the bearing and printed part, then use a slightly larger “L” sized part.

Service holes

BeltDrive 4x4 v1.1 features 3 service holes with covers. These holes have following purposes:

  • to help assembly of the gearbox; you can use the tip of the screwdriver to place belts in their position on the pulleys
  • allows you to check the internals of the gearbox without disassembling (heat, noises, wobbling, etc.)

Service holes are marked white on the picture below:

Is there any gap? Then use the “L” marked part!

Geared Gearbox – step 1/8

85

Put the gears onto corresponding shafts. Pay attention to combine the parts correctly!

Correct configuration

of gears is shown above.

Recommended material for gears: Fillamentum PLA Extrafill, Prusament PLA. Any PET-G will be too fragile for gears.

Use higher printing temperatures, about 210-215°C for PLA!

Top material choice for gears is Prusament PC Blend.

It’s very strong yet easier to print than Nylon, which is suitable too.

86 of 155

Geared Gearbox – step 2-3/8

86

Put the bearings on each shaft end. If you printed and checked the “Test part” with a bearing successfully, bearings should fit smoothly.

Insert shafts into the right side of the gearbox housing. Then apply grease on the gear tooths.

10x

Important! – for best gearbox endurance, use a lot of grease, as the grease will disperse the heat through the gearbox.

Motor pinion – version A:

use this pinion if you are using “round head screws”

M3 nut

Recommended material for motor pinion: ABS or CPE, as the PLA can melt due the heat from the motor shaft and PET is too flexible (pinion will slip from the shaft).

M3 nut

Insert nuts into the holes in the motor pinion.

Motor pinion – version B:

use this pinion if you are using “socket head screws”

Recommended material for “Gearbox housing - front”: ABS, ASA, CPE or PET-G, as the PLA can melt due to the heat from the motor if you drive continuously or in warm weather. It is strongly recommended to install an optional motor heatsink, preferably active! Purchase links are here or use any similar heatsinks.

active heatsink

passive heatsink

Test the gearbox before mounting to the chassis!

You should be able to turn the gearbox output shaft by hand with some force (attach Cardan Joint Yoke to the output shaft). After that, you can connect a 3 - 7 V battery directly to the motor, it should run.

Bamboo 4x4 – Axles choice

There are two different axles available for Bamboo 4x4:

With new Opened Differential

With No Differential (locked)

New Opened Differential features:

  • Medium print and assemble difficulty
  • Excellent for indoor driving and exterior hard surfaces
  • Excellent maneuverability and small turning radius
  • Low drivetrain/gearbox stress

Classic No Differential features:

  • Easier to print and assemble
  • Excellent for heavy terrain driving
  • Not recommended for hard surfaces (interior floors etc.) – using locked differentials on both axles results in high stress on drivetrain/gearbox parts.

Both types of axles can be combined to achieve optimum performance:

97

Front Opened Diff.

Ideal for interior driving or normal use on the yard

Rear Opened Diff.

Front No Diff.

Ideal for heavy terrain. Not for hard surfaces.

Rear No Diff.

Front Opened Diff.

Recommended setup – good on all surfaces

Bamboo 4x4 Pickup – general tips

  • Always use a proper battery charger. Bad charging of the Li-Pol battery may lead to a risk of fire!
  • Disconnect the battery when the model is not used. The small switch on the ESC doesn't disconnect the battery and the ESC may draw a small amount of current even in OFF-state.
  • Do not go into water unless you have waterproof electronics!
