What it does
- 8mm square beams with 5mm holes space 8mm apart, so you build robots that snap together like LEGO Technic
- Create custom sizes LEGO does not make, so your designs fit your exact vision
- Save money on building materials compared to LEGO, so you spend less while building more
- Print on demand means you get parts when you need them
Build your robot skeleton with Bitbeam. You get strong square beams that work just like LEGO Technic parts, so your creations stay sturdy and look great.
Each Bitbeam is an 8mm by 8mm square beam. Holes measure 5 millimeters wide and sit 8 millimeters apart. This matches LEGO Technic spacing exactly. You can stack beams, slot them together, and connect them to your LEGO collection without extra adapters.
The big win: you can make part sizes that LEGO does not sell. You pay less for materials than LEGO costs. Building your own parts is fun and teaches you how things fit together. We print your Bitbeams on demand from the US, so you order what you need when you need it.
