Welcome to the Official Underware 2.0 Channel Customizers! Developed together initially by Hands on Katie and BlackjackDuck and now receiving community contributions via our open GitHub library, this is a fully parametric version of the original Underware. 

Underware is the universal, open-source, modular, extensible and re-usable solution for managing cables, mini-pcs, usb devices…pretty much anything, anywhere!

New Features in 2.0: 

• Customizable Width
• Customizable Height
• New Mounting Options such as T Screw, magnets, wood screws, and adhesive!
• New Customizable Diagonal Channels
• New Customizable Y Channels
• New Customizable Mitre Channels
• Customizable Radius
• Customizable Corners
• Cable Cutouts
• Multi-color Labeling
• And more to come!

How to generate your own Underware

1. Click the Green 'Customize' button at the top of the page
2. Select the Component type you want to generate
3. Play with the options until perfect - click generate at any time to preview

Key Points

• Open-source design - The whole solution is open-source, so feel free to extend and come up with your own brilliant solutions.
• Parametric files - Customize your channels with over 10,000 channel variations without needing modeling skills or downloading CAD software!
• Printing - all files are printable as they are, without supports.

Mounting Options and Connectors

Threaded Snap Connector The threaded snap connector threads into the base channel and then snaps into a Multiboard. This allows for quick placing and removing channels, no need to remove adjacent channels, and allows for offset from board to traverse dual snaps and other obstacles.
	Split Printing - NEW FEATURE!   Allows for splitting the part so that layer lines contribute to thread strength. This dramatically improves snap strength for repeated adding and removing of threaded snaps.
	Snap Connector Height (Offset from board)   Change the gap between the base channels and the mounting surface. Default is 3mm to match standard Multiboard offsets and to traverse over dual snaps that connect Multiboard tiles.  If mounting Multiboard tiles using screws and not using dual snaps, set the Snap Connector Height to zero to save filament and have a truly flush set of Underware.
	Snap Holding Tolerance and Oct Scaling   Connection too tight or too loose? Adjust the bump-outs (Snap Holding Tolerance) or the entire octogon (Oct Scaling) to a better fit.
Bolts Bolt mounting screws through the channel into the Multiboard small threaded hole. This approach saves filament while offering a very strong connection. A tool is included to aid screwing and unscrewing.  Note - This mounting method does not allow channel offsets from the board. If you mount your tiles using dual snaps, you will not be able to traverse dual snaps as they stick out from the board unless you extend the length of the bolt.
	Thread Length   Change the length of the thread. Default is 6.5 which allows for strong connection through a channel and into a board. Add additional millimeters if needing to offset (although connection will be loose).

Available Channels

I-Channel (Straight)
	Length, Width, and Height   Note - Tall channels will have reduced holding strength due to flexing.
	Cord Cutouts   Add cord cutouts to the top channel for cord entry and exit. Change number, spacing, width, and positioning.
	Text Labels   Add text to your top channels in color, depth, or both. Note - Font examples here are Raleway and Oswald
L Channel (Turn)
	Length, Width, and Height   Modify channel length, width, and height. New Feature - Each side can now be edited independently.
	Zero Lengths - New Feature Change a length to zero and the channel will properly render for an edge of desk exit or flush turns to a different channel.
C-Channel (Curve)
	Width and Height
	Radius    Change the radius for wider turns.  Note: A radius of 1 can be mounted directly against a radius of 2 and so forth if the width is 1. If the width is wider, be sure to multiply the radius by the width. For example, a channel width of 2 will require a radius of 1 to be next to a radius of 3.
T-Channel
	Width and Height
	Sharp and Mitered Corners (New February '25)
X-Channel
	Widths and Height   New feature - Change widths independently for different-width intersections.   Add height for more room.
Y-Channel
	Width, Height, and Length
	Output Direction   Change whether the outputs continue forward or turn outward.
	Straight Distance    This is the length of the straight section before the turns. Note, wider channels may produce artifacts. Changing this straight distance often resolves them.
Diagonal Channel
	Width, Height, and Length
	Output Direction   Change whether the outputs continue forward or turn outward.
	Straight Distance    This is the length of the straight section before the turns. Note, wider channels may produce artifacts. Changing this straight distance often resolves them.
S-Channel (NEW!)
	Width, Height, and Length
Height Change Channel (NEW!) Note: Due to shape, the top needs to be printed in the orientation shown. Some printers may require brim setting to be turned on.
	Length and Width
	Height 1 and Height 2
Mitre Channel
	Width and Height
	Distance from edge    This value calculates (in mm) the distance from the corner to the end of the piece. Each sides are independently configurable. This value automatically adjusts when heights are changed to maintain the same mm.

Mounting the Item Holder?

I recommend DavidD's flush mount Multiconnect for Underware as this provides the most secure fit. The only time this will not work is if you mounted your Multiboard using snaps and your Item Holder needs to sit on top of them. If this is the case, use the standard Multiconnect.

Mounting on Multiboard? Base Multiboard grid available here:
