2026-01-17 Update: Slight adjustment to dimensions with openConnect release.

2025-08-08 Update: The project is now in OpenSCAD. You can customize it to make coin screwdrivers of different size/thickness.

I designed this to install openConnect/multiconnect connectors on openGrid. The hex bit can also function as a general coin screwdriver.

Can be used with any tool that takes a 6.35mm hex bit. Optionally, glued a thin metal plate to the bottom so it can be attracted by magnets.
 

为了在openGrid上安装multicunnect设计的批头。根据multicunnect的尺寸设计，也可以用在其他硬币形的槽口。

兼容使用任何6.35mm批头的工具。可在底部粘一片金属片以方便磁铁吸附。
