Attaches to standard LittleBits side connectors and provides several standard Lego technic style axle holes to fix into a frame. Print 2x adaptors for each LittleBits part you need to attach. Some Items Like the LittleBits speaker may need the top tab snipping of to fit on (they still clip in rather nicely without this) Theoretically should work with 90deg connected Littlebits parts also with a bit of clever Lego building. Will be uploading a version with a standard 9v battery holder shortly to go with this. Follow us on twitter.com/strangeflavour or visit our website www.strangeflavour.com for more upcoming projects!
