+--- Thread: Duplo brick runner assembly (/thread-28968.html)
Duplo brick runner assembly - Peter Blomberg - 2025-07-29
The brick runners (e.g. 31202c04) are assemblies consisting of one base, four wheels, and two axles.
The base has 31202 embossed onto it and 5436 printed with black ink.
Each wheel has 31204 embossed on it.
The metal axles have no visible part numbers.
What is the part number for the chassis/base to be used in LDraw?
What is the assembly number to be used in LDRaw?
Shall the c01... follow the same logic as in BrickLink?
What u number can I use for the metal axles and which color would I make it?
Is there any special way to mark these parts as members of assemblies/shortcuts so that they do not get used outside any assembly?

Quote:DUPLO Parts are referenced since LDD 2.3 (Part: 23065, Ball 52mm), meaning that most likely LEGO internally has digital versions of most of their parts since a long time. Other DUPLO parts which are referenced are 71956 (DUPLO BRICKRUNNER, AXLE - which is part of an Assembly I guess), 95109 (LIPSTICK, CORE - also part of an Assembly I think) and 10888 (DUPLO TURN BRICK 2X2)

31202 is the design ID for the chassis. No idea what the printed number means.

Put a "~" before the name. This makes the relevant part invisible for parts bins etc.

The base is 31202.
This assy is 76139
https://brickset.com/parts/design-76139
The axle is 71956. Use colour 494, "Electric_Contact_Alloy" (in the wheel+axle assy)
The wheel+axle assy would be 71956c01
Use a ~ in the descriptions of all parts except the full assy 76139
RE: Duplo brick runner assembly - Peter Blomberg - 2025-07-29
Trying to summarize:
In default colors (16, 24):
31202 ~Duplo Brickrunner Car Base 2 x 4
31204 ~Duplo Brickrunner Car Wheel
71956 ~Duplo Brickrunner Car Axle
For each wheel color:
71956c0_ ~Duplo Brickrunner Car Axle with ___ Wheels
Wheels in ___ color and axle in color 494.
76139 Duplo Brickrunner Car Base with Wheels (Is this needed at all?)
All subparts in color 16?
Is a 71956 with default colors needed?
For each wheel color:
76139c0_ Duplo Brickrunner Car Base with ___ Wheels
Base in default colors
Use matchin axle+wheel assembly 71956c0_

76139 Duplo Brickrunner Car Base with Wheels (Is this needed at all?)

then make one fully col16 car base assembly and one for each wheel color. (base always col16)

Trying to summarize again:
In default color 16:
31202 ~Duplo Brickrunner Car Base 2 x 4
31204 ~Duplo Brickrunner Car Wheel
In color 494:
71956 ~Duplo Brickrunner Car Axle
In color 16:
76139 Duplo Brickrunner Car Base with Wheels
consisting of
1x 31202 in color 16
4x 31204 in color 16
2x 71956 in color 16 (494 was hardcoded so this won't override it)
For each wheel color:
76139c0_ Duplo Brickrunner Car Base with ___ Wheels

4x 31204 in color ___

RE: Duplo brick runner assembly - Peter Blomberg - 2025-07-30
It is more complicated. There are 6 wheel colors and one of them have a pattern on the wheels.
The base/chassis has a pattern in two out of six cases.
Here is what I have:
- Part 71956 ~Duplo Brickrunner Car Axle harcoded in color 494.
- Part 31204 ~Duplo Brickrunner Car Wheel.
- Subpart 31204s01 ~Duplo Brickrunner Car Wheel - without Patternable Surface.
- Part 31202 ~Duplo Brickrunner Car Base 2 x 4.
- Subpart 31202s01 ~Duplo Brickrunner Car Base - without Patternable Surfaces.
- Subpart 31202s02 ~Duplo Brickrunner Car Base - Half without Patternable Surfaces.
- Subpart 31202s03 ~Duplo Brickrunner Car Base - Base Quarter without Patternable Surfaces.
- Subpart 31202s04 ~Duplo Brickrunner Car Base - Wheel Holder Quarter.
- Shortcut 76139 ? Duplo Brickrunner Car Base with Wheels
- Shortcut Physical_Colour 76139c01 Duplo Brickrunner Car Base with Dark Gray Wheels
- Shortcut Physical_Colour 76139c02 Duplo Brickrunner Car Base with Very Light Bluish Gray Wheels
- Shortcut Physical_Colour 76139c03 Duplo Brickrunner Car Base with Black Wheels
- Shortcut Physical_Colour 76139c04 Duplo Brickrunner Car Base with Dark Bluish Gray Wheels
Here is what I suspect might be needed:
BrickLink 31202c05pb01: Lime wheels and patterned base
- Shortcut Physical_Colour 76139c05p01 Duplo Brickrunner Car Base with Lime Wheels and xxx Pattern
BrickLink 31202c06pb01: Patterned wheels and patterned base
- Part 31204p01 ~Duplo Brickrunner Car Wheel with xxx Pattern
- Shortcut Physical_Colour 76139c06p01 Duplo Brickrunner Car Base with Yellow Wheels
Should the default colored assembly 76139 have a tilde~ in its description? Why is 76139 needed?
Are patterns parts or shortcuts?
RE: Duplo brick runner assembly - Rene Rechthaler - 2025-07-30
All single parts (Axle, Wheel, Base) are color 16.
axle and wheels should be in an axle+wheels shortcut (1 axle hardcoded 494 and 2 wheels col16)
the car base shortcuts could be just col16 base and 2 colored axle shortcuts.
are there two wheel types? 31202c03pb01/31202c03pr0001 looks like its mixed: wide wheels with print and normal thin wheels...
Are patterns parts or shortcuts? can be both, the pattern itself goes onto a single part, that patterned part can then be in a shortcut. there shouldnt be manually drawn patterns in shortcuts.
Will the wheels be standard res or hi-res? should be possible to use prims...
RE: Duplo brick runner assembly - Orion Pobursky - 2025-07-30
I'll read over rest here in a bit but one thing stood out on a skim through:
Physical_Colour is depreciated. The PT will reject your part if you use it.
RE: Duplo brick runner assembly - Magnus Forsberg - 2025-07-30
First of all. "Physical_Colour" is an abandoned branch of files we don't want.
Here is how I think it should be made:
Three parts; Body, Axle, Wheel (with some variants), All should be made uncoloured.
Axle.
71956
This axle will be the base for a number of different assys (shortcut), where the axle is used coloured 494
-c01, thin wheels, no pattern
-c02, thick wheels, no pattern
-c03, thin, or thick wheels with pattern A
-c04, thin, or thick wheels with pattern B
Body
31202
-p01, body with pattern A
-p02, body with pattern B
Wheel
31204, thin wheel
-p01, Are there any thin wheels with a pattern?
Wheel
?????, thick wheel
-p01, thick wheel with pattern, but wheel is uncoloured, to be coloured in a later assy.
Assys
76139, this is a uncoloured base shortcut, using a uncoloured body + uncoloured thin wheel assy c01
76139p01, uncoloured base + coloured wheel assy (grey, or any other colour)
76139p02, uncoloured base + coloured wheel assy (e.g. black)
76139p03, uncoloured base with a pattern (31202p01) + coloured wheels
76139p04, uncoloured base + coloured wheels with a pattern 71956c03.
XXXXX
-p01, uncoloured base + uncoloured thick wheel assy c01
We need to know 3 things:
- Partnumber for the thick wheel
- Partnumber for the assy with mixed wheels
- Partnumber for the assy with thick wheels
76139 is an assembly number. It's not possible to add a -c01 suffix to it.
(it would be like saying "CD-disc", a "compact disc-disc" )

Bricklink says the wide wheels have 92587
https://www.bricklink.com/v2/catalog/catalogitem.page?P=31202c03pb02&idColor=11#T=C&C=11
do the black/black bases count as uncoloured with uncoloured wheels or black wheels?

92587 is a "Wheel Ø17". Could be the right one.
95118 is "BRICKRUNNER W. 2 Ø17 WHEELS"
95485 is "BRICKRUNNER W. 4 Ø17 WHEELS"
Black wheels on a black body should use the uncoloured assy.
