Leapfrog Creatr Top Bracket
This is a general purpose bracket for the top of the Leapfrog Creatr.
The current design has two holes which are offset from the center for mounting a Raspberry Pi. The holes are designed to hold a nut precisely from the bottom of the bracket.
Here's an online version that doesn't require an account to remix.
