The carefully selected list of blocks leads to individual user-friendly models and creations.
Thanks to the limited number the necessary blocks are found very quickly and can be built faster. However, this number is not too small to have sufficient construction possibilities to demonstrate the many technical and machining concepts.
This block list contains different types of gears so that all proportions and angular connections are possible. You can also add your own material such as elastics, rope or paper,to make even nicer models.
If you already have some building boxes, you probably already have a part of our Heliwi blocks list. If you are missing some blocks, you can complete the list via Bricklink.
