Before you start

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

Please at first test whether the bearing can be inserted into the calibration part. If you have problems or the bearing fits too loose, please make sure that the printer is properly calibrated. Dimensions of the printed parts should match dimensions of the 3d model.

At first, you will make a “glass” from any transparent foil up to 0.5 mm thick. Thicker material is more durable than thinner, but we found that “Clear Binding Covers” are OK.
Place the printed template on the foil, sketch the shape to foil and then cut the foil by scissors or sharp knife.
3d print the template and then use the sheet of transparent foil, max. 0.5 mm thick.

Bamboo 4x4 – Gearbox choice
There are two different gearboxes available for Bamboo 4x4:
new BeltDrive 4x4
classic Geared Gearbox
New BeltDrive 4x4 features:
New BeltDrive 4x4 is recommended choice. It can handle more power (up to 3S battery) and is very silent. It is compatible with all 3D Sets 4x4 models.
For BeltDrive 4x4, proceed to next page (55).
Classic Geared Gearbox features:
Classic Geared Gearbox is good choice if you have previous experience with and if you require 540 DC 27T motor and maximum precision of throttle response.
For Geared Gearbox, proceed to page 71.

BeltDrive 4x4 Gearbox
Required print plates:
Non-printed parts:
In this 8-step procedure you will assemble belted gearbox with the motor. The whole gearbox can be printed from PLA, unless you will drive in some extreme conditions or in very hot environment. To complete this task, get the following parts ready:
55
Shafts

If you will print the part “Shafts” from the .stl file instead of printing from provided gcode, please use following slicer setup:
correct printing bed orientation of the Drive Shaft - Cardan and Front Wheel Shaft – marked part MUST LAY FLAT on the bed!

BeltDrive 4x4 Gearbox – introduction
59
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:
Important features
60
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:
Service holes are marked white on the picture below:
Is there any gap? Then use the “L” marked part!

Be careful – do not damage the “ball” part!
Geared Gearbox – step 1/8
73
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.
Geared Gearbox – step 2-3/8
74
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.

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”
Geared Gearbox – step 6-7/8

Now mount the motor and bearings to their positions. Then install the motor pinion on motor shaft.

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.
