Gridfinity Basket in OpenSCAD

An openscad script for stackable baskets with a gridfinity base on the inside. Includes many customization options.

The model and various example baskets are also available on makerworld/printables. The site on makerworld also supports the parametric model maker to easily create baskets with different options directly on the site.

Customization options

Below is a list of all possible customization options. Although it is possible for most options to set a value outside of the allowed range, in almost all cases it is not a good idea.

General options

Parameter	Description	Type	Default	Allowed Values / Range
UseMulticolor	Add color to the model in three different sections (Can be used together with the openscad .3mf export for multi-color printing)	bool	false	true, false
UseGridfinityBase	Include a Gridfinity base inside the basket or keep the bottom flat	bool	true	true, false
GridSize	Grid size in [X, Y, Z] format, in multiples of 1U gridfinity units	array	[2,2,4]	Integers ≥ 1
Padding	Padding between edge of Gridfinity base and basket walls (zero padding makes bins with the same size as the basket hard to put in/take out)	number	1	0 to 10, step 0.1
WallThickness	Wall thickness of the basket	number	1.2	0.4 to 2, step 0.1
AdditionalFloorHeight	Additional floor height added to bottom of basket	number	1	0 to 3, step 0.04
SolidFloor	Make floor solid (requires FloorHeight > 0)	bool	true	true, false
MagnetDiameter	Diamenter of the magnets. If set to zero, no magnet holes will be created. Increase this value to add some tolerance for magnet insertion.	number	6.5	0 to 8, step 0.05
MagnetHeight	Height of the magnets. If set to zero, no magnet holes will be created. Increase this value to add some tolerance for magnet insertion.	number	2.1	0 to 4, step 0.05
AddMagnetChamfer	Add additional chamfers around magnet holes to help with insertion	bool	false	true, false

WallPattern options

Parameter	Description	Type	Default	Allowed Values / Range
WallPattern	Wall pattern type	int	1	0: None, 1: HexGrid, 2: Grid
PatternSize	Pattern feature size	number	8	4 to 15, step 0.5
PatternTopDist	Minimum distance from the top of the pattern to the start of the stacking lip	number	3	0 to 10, step 0.1
PatternBotDist	Minimum distance from the bottom of the pattern to the baseplate	number	1.5	0 to 10, step 0.1
PatternSideDist	Minimum distance from the pattern sides to the start of the basket outer corner	number	2	0 to 10, step 0.1
PatternMinDist	Minimum distance between patterns	number	2	0.5 to 5, step 0.1
GridPatternRadius	Outer radius of grid pattern (not applicable to other patterns)	number	3	0 to 10, step 0.5

Handle options

Parameter	Description	Type	Default	Allowed Values / Range
AddHandle	Add a handle to the sides of the basket	bool	true	true, false
HandleWidth	Width of the handle	number	35	20 to 100, step 1
HandleHeight	Height of the handle	number	11	11 to 30, step 1
HandleCorderRadius	Radii of the corners on the inside of the handles	number	4	0 to 5, step 0.5
HandleBorder	Minimum border size around the handle. The border may be larger to accommodate the wall pattern	number	3	2 to 5, step 0.5

Stacking options

Parameter	Description	Type	Default	Allowed Values / Range
Standoff	Vertical standoff height at the bottom of the basket (the part that sticks into another basket when stacked ontop of eachother)	number	1	1 to 2, step 0.1
TopPadding	Extra room above bins for stacking	number	2	0.5 to 5, step 0.1
XYTolerance	XY-axis tolerance (should keep as-is in most-cases)	number	0.5	0.2 to 1, step 0.05
ZTolerance	Z-axis tolerance (should keep as-is in most-cases)	number	0.25	0.25

Additional tips

• The Grid pattern can be quite fragile. Use a large PatternMinDist and possibly a larger WallThickness.
• No need for supports or brim when printing the baskets.
• The HandleBorder sets the lower limits for the border around the handle. It might be increased so that the chosen pattern and the area for the handle line up. Otherwise the border of the handle could be floating and couldn't be printed without support.

Acknowledgements

The base generation is inspired and adapted from the gridfinity-rebuilt-openscad project.

The general idea is based on the Gridfinity-baseplate-basket-parametric model by Blaise's Workshop. In comparison to that model, the gridfinity basket here offers much more customization options and various improvements like the support for padding and different wall sizes.
