Mobaco with round towers
When I first knew about Mobaco, I was dreaming about creating big castle's, with towers and gates. But how to add these elements gently into the Mobaco ecosystem? Mobaco is having floor plates with square hole patterns, fitting columns and wall panels. So basically only retangular type buildings + tower segments could be created. It's […]
Online 3D model viewers...
Creating those LeoCAD 3D buildings/structures, will be more appealing, when viewed inside a 3D viewer, so it's time for some coding.Since glTF is "the standard 3D format" for internet and could even include animations, this seems a good direction to try. Converting LeoCAD to glTF With a bit of help from ChatGPT, managed writing some […]
Mobaco - Doors & Gates
It's still funny to see what the boys are creating with Mobaco. The doors & gates are always used. Somehow they like this simple addition. So after a request for new wall pannels, it's also time updating the gates: The wooden parts from the left 2 buildings were already made. Main concern: "The double doors […]
Mobaco Model 4-78
Time to create some virtual Mobaco models. Let's go for the bigger bit strange: Set 4, No. 78. For some reason, the mid section of the building is floating. The building plan: It's having some interesting column supporting structures. The center of the buildings doesn't have any supports to the ground. At floor leves VI, […]
Dom Tower & Church
Project: Swiss cheese. It's finaly time, recreating a Mobaco model on my own. After visiting the beautiful Dom Tower in Utrecht, we bought a puzzle version for our kids... That's a nice start, understanding the properties of the church, at least, that is what I was expecting.. Dom Tower - Top section Since the Dom […]
Cathédrale Notre-Dame de Paris
L'Edifice: Already in the prototype exhibited at the Concours Lépine in 1920, there was a cathedral, most likely symbolizing the Cathédrale Notre-Dame De Paris. Later, there were 2 versions sold. The left side could be found in 1922 manual and the right version around 1925. Also these models are remodelled into LeoCAD: Mobaco: What happens, […]
Pulko Patent Baukasten - Reproduction
Pulko Bauhause style... Enthousiast about the new findings of the Pulko patent, it's nice to re-create these Bauhaus style panels in real. Since I'm less interested, in rebuilding the whole system, it's scaled to Mobaco, so baseplates & columns could be re-used. Besides that, the difference in bay size is only 2.5 [mm] width. With […]
Mobaco 100 Years
This year Mobaco celibrates its 100 years of existing, turning a vintage toy into an antique toy... So it was time for creating nice presents for both Nick & Caspar during this special 100 years Mobaco. Not only for their part of researching Mobaco, but also organising some Mobaco exhibitions, still sharing new Mobaco findings […]
Reconstruction Model-Z
Model Z was issued around 1931. Unfortunately this set is never produced. Together with C. Mol, we reconstructed these exciting 'new' elements. There are 3 examples found, where the new constuction elements were used. And simular LeoCAD models were created: Or see this 3D model: After some iterations it was time build these parts in […]
Retro Building Toys
Around April 2021 I came in contact with a small group of enthousiasts, who were investigating an old Dutch made construction toy called: Mobaco (1924-1956). After reading some posts & discussions, I wanted to anticipate to this research, but from a bit different angle: Why not make this building toy available in 3D, so everyone […]
