When I was young, I played a lot with LEGO® and started my Technic build with the Farm Tractor #851.
And, as many youngsters, I left the LEGO® bricks alone as my interest shifted into performing sports (swimming, cycling, running), IT technology education, and having a good time with friends in Clubs and Pubs.

After graduating and starting my work-carreer as an IT professional at the #1 Supermarket company in The Netherlands, I slightly developed the thought to restart the Technic LEGO® hobby again. However, it took a couple of years before I turned this into practise; actually till the Mobile Crane set #8421 launch in 2005. I bought this set to figure out what 'step change' LEGO® had achieved compared to the Farm Tractor #851 launched in 1977.

I was amazed by the significantly improved LEGO® Technic parts; providing the ability to design complex technical functions.
And given my IT background, I came across the existence of computer aided design (CAD) programs as MLCad, LDview, Lpub and POV rendering. This made it possible to create your own building instructions in a professional way.

So, I decided to glue things together: At one hand, designing LEGO® models based on replica's of existing vehicles, with reliable technical functions and a smooth appearance. At the other hand, show-case the models by leveraging Digital technologies: Create Building Instructions, This website, Social Media and Payments integrations. The last one, selling Building Instructions is just to compensate my effort and is full reinvested into LEGO® Bricks for the next model or in LEGO® sets for my kids.
The 'design frequency' for a new model is mostly once a year during winter-time, as free time is the biggest constraint.

For years, the Prinoth Leitwolf snow groomer (2007) ranked my personal 'flag-ship' position, succeeded in 2018 by the Cable-system Container Truck. However, since 2024, the Prinoth Leitwolf R3 version holds the 'flag-ship' position again; given the extra added features and strong powered performance based on BuWizz® 3.0 or LEGO® Power Functions.
