Gridfinity implementation containing:

- Ultralite Bin - Basic bins designed to reduce filament usage.
- Flat-bottomed Bin - Same as the Ultralite bin, but with a smooth bottom.
- Circular Bin - Bins designed for holding circular objects like bottles.
- Ultralite Circular Bin - Same as the Circular bin, but with reduced filament usage.
- Baseplate - Standard Gridfinity baseplate
- Grid Filler Baseplate - Fractional sizes of grid cells to fill in edges.

All parts are configurable in OnShape. So you'll need an account there to get access.

I'm often adding new designs and fixing issues I find, so I recommend always using my document to generate parts you need instead of copying the document.

Individual parts are organized into folders accessible from the bottom bar. Configurations can be adjusted in the top left corner as described below.

Note that the parts added here in printables, are only examples of what can be created from the OnShape documents. Any special parts you need should be generated from OnShape.

- XSize - Number of grid cells wide this bin is. Each grid cell is 42mm. Does support fractional sizes like 2.75. In practice, anything other than 0.25, 0.5, and 0.75 fractional sizes aren't recommended.
- YSize - Number of grid cells deep this bin is. Each grid cell is 42mm. Does support fractional sizes like 2.75. In practice, anything other than 0.25, 0.5, and 0.75 fractional sizes aren't recommended.
- ZSize - Number of units tall this bin is. One unit is 7mm. Measured from the very bottom of the bin to the top.

- ZSize - Number of units tall this bin is. One unit is 7mm. Measured from the very bottom of the bin to the top.

- Diameter - Diameter of the circular insert.
- ZSize - Number of units tall this bin is. One unit is 7mm. Measured from the very bottom of the bin to the top.
- AllowFractionalSizes - If checked, the size of the bin will be rounded up to the nearest 1/2 grid unit.

- Diameter - Diameter of the circular insert.
- AllowFractionalSizes - If checked, the size of the bin will be rounded up to the nearest 1/2 grid unit.

- LabelWidth - Number of grid units wide to make the label feature.

- XDividerCount - Number of divided areas in the x direction.
- YDividerCount - Number of divided areas in the y direction.
- DividerZSize - Height of the dividers generally this should be ZSize - 1 units.

- XSize - Number of grid cells wide this grid is. Each grid cell is 42mm.
- YSize - Number of grid cells deep this grid is. Each grid cell is 42mm.
- GridSizeMultiplier - The base unit of 42mm is multiplied by this integer. Ie a 2x2 grid with a multiplier of 1 will be 84mmx84mm. A 2x2 grid with a multiplier of 2 will be 168mmx168mm. This value is useful if all your bins are larger than 2 units. This significantly reduces the time it takes to print.

- XSize - Number of grid cells wide this filler is. Each grid cell is 42mm.
- YSize - Number of millimeters deep this filler is. Given an area of 100mmx100mm, you can print a 2x2 standard grid, then print 2 2x16mm fillers to prevent the baseplates from sliding about.
