KRB - Kraken rockets blocks - Classic pack

KRB was originally created as a toy for my children, so I could share something I loved with them – a passion for rockets, space.

After several trials, I developed a system of smaller magnets that allows rocket parts to be connected at different angles and with varying diameters.

The flat magnet-to-magnet connection allows for quick and simple rocket assembly, as well as RUD – rapid unplanned disassembly. Which is actually the point of the kit.
Build it, launch it, break it.
Kids learn that different parts have different connection strengths, and more complex and chaotic rockets are more vulnerable to Kraken strikes and total disintegration.

As a parent, I recommend that children play with the kit under supervision, and that all pieces be checked for damage after each play session.

Magnets must definitely be glued in if you plan to use the kit with children.

3D model how to assemble magnets and push fit tool is in Tool pack:

For this purpose, the magnet socket is designed to secure the magnet in place using side wedges after glue is applied. It also ensures the correct depth and prevents air pockets from pushing the magnet out.

Any excess glue or print inaccuracies – I recommend sanding with sandpaper – this greatly improves the fit and durability of the connections.
