“The Mobaco system consists of square wooden columns of various lengths that fit into evenly spaced holes in a thick fiberboard base board. The columns have slots on all four sides, into which dense cardboard panels are slid. The panels have different colors, and are either solid or have window or door cut-outs of various shapes.

The system allows for pitched roofs. There are special gable ends and purlins that form the structural support for the roof. Opposite roof panels interlock at the ridge with hooks, and hang from the ridge beam.”

Building with Mobaco

More information on building instructions in real life. You could also try to build these examples, from the never produced box no. 5:

Reconstruction Model Z

Besides putting the existing parts into 3D, it’s also fun to research and virtualize those advertised, but never produced parts!

This is a nice example of Model Z, which was issued around 1931, but never produced. Together with C. Mol, we reconstructed these exiting new elements.

And not only that, also bring them (back) to life, by building them in real models:

The 3 roofs could also be modified from existing Mobaco roofs: 103, 123 & 124. This will give a nicer ‘Mobaco’ look. In this case, the wooden parts could be used as overlay.

Currently also selling ao. the special Model-Z parts. The Ikea hardboard is gone by now, so now re-creating parts in wooden (2mm) version:

This very nice model is created by Pim ten Have, using a Model Z set.

Custom parts, specials & rare parts

Beside Model-Z, I’m also creating other custom parts on demand, like: ‘rare’ roof parts #150, #151, #152; bigger base plates (6×8, for the garages), special windows (see: Other Special Parts), laser engraving like the big clock (#29). Different engravings -texts/pictures/photo’s- are possible too.

Requested by my kids: prison panels, which is a nice addition.

When Mobaco was sold under Jumbo licenses, they also pictured a smaller windmill. Although these parts are numbered on the content inside the lid, these parts are never found. So again, it was time for a re-make.

The farm was recreated from pictures found on MP. This might have been a Mobaco prototype but we are not sure. If you know this model, please let us know. Anyway it’s a nice model.

If you are interested in some parts, just send me an email and let’s discuse the details.

Mobaco timeline

Buildings created by various enthousiasts, including myself. =)

A nice overview, of both realized buildings and their digital counter parts, all available in LeoCAD.

Since all panels are stamped parts, making a lot of these metal stamping tools must have been taken place before 1924 and would have cost a lot of money. It’s still unknown, who is involved for making this nice building toy.

In this case the LeoCAD system was also used by a designer, for recreating the Maliebaan Train Station in Utrecht (model bottom right side) and was rebuild & styled by an other Mobaco enthausiast.

Mobaco Universe…

A collection of all known virtual builds:

And still expanding. Even gnomes are helping now, building the latest models…


Mobaco is a nice game to build/play with. Most pannels fit well in the columns and building is quite rapid. The kids never build from the manuals, which is fine. The only issue we encounter is the ground plates. When sticking columns in the ground plate, they will mostly tip over. (Especially the 12mm columns in the older base plates.) After the first floor is created, it’s more easy to build.

Tatami does a great job, by re-selling Mobaco like game, with a better ground plate, including a closed holes.

There are many occasions when we are building Mobaco, mostly incombination with other toys…
