Plank Hole drilling Jig For Building Blocks

Thank you for watching. This is a video about how I produce the plank components for a building blocks system I am prototyping but released to the public for their entertainment. Feedback in the comments would be greatly appreciated. More videos on the project to follow.

Constructed of 3D printed blocks, plastic nuts & bolts and MDF planks the purpose of this project is to bring theories off the page or screen and into a real experience for my nieces and nephews. Files and a pamphlet can be found at:

The safety of the parts or designs cannot be guaranteed and are released for entertainment purposes only.

I used hardware from McMaster-Carr.
