Multiconnect Part Generator - Master Collection

LOOKING FOR openGRID? Check out the new MakerWorld model page just for openGrid parts! openGrid Part Generators - Vertical Mount Series - Free 3D Print Model - MakerWorld

Rapidly create custom rectangular bins, shelves, item holders, and hooks for your multiconnect/multiboard system! Each part is customizable to your needs and automatically adds the appropriate multiconnect slots on the back. 

This collection includes all of my parts in a single page. Want to comment or support specific parts? Find them in my Multiconnect Part Generator Collection!

Available Part Types:

• Gridfinity Shelf (new!)
• Round Item Holder (new!)
• Round Items Row (new!)
• Flat Shelf
• Bin
• Item Holder
• Hook

Narrow Parts?

If your holder is narrow with only one multiconnect slot, I remixed a non-rotating threaded connector for Multiboard. You can use any multiconnect holder to crank it down so your parts don't rotate. 

Documentation

Documentation is available, but extremely limited. Most parameters should be self-explanatory. I will continue to develop the documentation as I get to version 1.0.  

Background

Anticipating our first child, we realized that we needed much better organization. Thanks to Reddit, I found Hands on Katie with an organization structure that resonated. She recommended an approach that, when combined, take care of most storage needs: big, small, horizontal, and vertical. It consists of Multiboard, Multiconnect, Neogrid, Gridfinity, Underware Cable Management, and French Cleats.

I dove head-first into the first category: small things on the wall with Multiboard and Multiconnect. But I quickly encountered a problem - I was spending a LOT of time either looking for the holder that I needed or uniquely designing for each and item. It started with rectangular items where I found myself only tweaking a few spots in Fusion 360 and adding/removing Multiconnect slots. I kept thinking that there has got to be a better way to make these adjustments. Then I learned of parametrics: designing in such a way that parts are rapidly customizable by entering a few parameters and the rest of the object dynamically changing to accommodate those parameters. 

It started in Fusion 360, which is very powerful, but as I made my first models I developed 2 goals: (1) I wanted to share them with the community and (2) I wanted it easily accessible to everyone (and I knew the pain and hardware requirements of getting Fusion 360 up and running with the hobby license). Here comes OpenSCAD and MakerWorld: a way to programmatically design and host parametric 3D objects.  

This is the result of that goal - fast, standardized, and web-based methods of generating the exact holders you need in a one-stop shop.

Multiconnects

These items use DavidD's multiconnect system. It takes the multiconnect slot (and options) and places them where needed along the back of this part. You can find DavidD's parts here: https://www.printables.com/model/716558-multiconnect-generic-connector-for-your-board
