Custmizable Spacebar Keycap Generator SA Profile 3D print model

This is a completely customizable, higly refined, fully parametric keycap generator for spacebars made in Fusion 360. You can easily customize the geometry by changing just a couple numbers in the parametrs.

You will need Fusion 360 to customize (free software) but there are many STL files included as well including widths of 6.25U, 6.5U, 7U and Corsair 6.5U versions.

This is based on the SA profile created by signature plastics. This profile is sculpted meaning that each of the 4 keyboard rows have different angles and heights. This design builds on that and adds Row 0 and Row 5 which continue the curvature.

There are 4 parameters representing row 1-4. Just set a value of 1 for whichever row you would like to make a keycap for, and make sure to set a value of 0 for all of the other ones. This will automatically modify the angle, concave and height of the keycap for that row. That easy! Row 3 is the default for spacebars but I like to use Row 2 shape since it curves towards you, giving a nice smooth edge for your thumbs.

Instructions:

1. Register, download, and install Fusion 360 (https://www.autodesk.com/products/fusion-360/students-teachers-educators)
2. Open the .f3d file in Fusion 360
3. In the Design environment click MODIFY -> Change Parameters
4. Adjust the U_Width (1 for normal keys, 2.25 for a 2.25U shift key etc.)
5. Edit the Sketch Text sketch - Right click on the example text and click Edit Text and change to your liking. Adjust the box around the text if needed so it is centered
6. Set a value of 1 to the Row parameter you would like to make the keycap for and set 0 for all of the other rows
7. Change any other parameters you want including, Concave, MXHoleTolerance (increase for FDM printers) etc. If you don't want the ribs, right click Reinforcing Rib group and select Suppress features
8. Right click on the main component (Key Generator Super SA) and click Save As STL, and export to your desired location
9. Slice in your desired slicer, send to 3D printer and enjoy your new key! If it doesn't fit, try increasing or decreasing the MXHoleTolerance parameter slightly. Play around with the parameters for different shapes! If you break the model, just hit undo until its back to normal.
