OEM Key profiles were measured off of a set of Vortex PBT Doubleshot 104-Key caps.
Cherry Key Profiles were estimated off of Cherry Corp. datasheets.
Files were made using Solidworks 2017.
This readme shows the keys available in each layout pack, and then walks through the process of modifying dimensions on original Solidworks files.
Each key in each pack is selectable as a configuration within the solidworks part file.

Modifying Base Dimensions on Wookiee’s Keycaps Files
Base key dimensions are 18x18. Including these dimensions in configurations and design table allows me to switch between any key width and length.
Front plane angle is set coincident with front edge of base, and at an angle. This angle can be adjusted for all configurations, or you can add it to the design table and set different angles for each configuration.
The angle of the rear plane is set the same way, but references the rear edge of the base sketch.
The front and rear height of the profile are set using a construction sketch on the right plane. These dimensions are constrained to the front and rear angle planes, and set as distances from the base plane. They are included in the design table and set in each configuration.
The shape of the top of the key is set by an extruded loft between the two angled planes. The front edge is defined on the front angle plane. The width is defined relative to the base, the endpoints are set by the previously sketched profile, and the depth is dimensioned to the midpoint.

Theoretically, this means you can make the front and rear of the keycap completely different shapes. Just be careful, in the published .sldprt files, changing the shape in one dimension will change it for all dimensions.
A loft between the base sketch and the lofted top profile gives the key shape. This is then shelled. The wall thickness is defined by the shell.
The upright edge fillets are set using a multiple radius fillet. Each edge can be edited individually.
The top edge has a tiny fillet put on it. This is for aesthetics and can be suppressed or changed at will.
The stem shape is defined on the bottom plane, and extruded up to surface to the top surface. These dimensions can be easily changed. I used 1.2mm wide x 4 long for the arms of the key cross.
The stem opening is chamfered per the Vortex model these were measured from.
Stems for stabilizers are spaced using linear patterns which are suppressed or activated by configuration. Key widths 2u and up have stabilizer stems, shorter key widths do not.
Each SLDPRT file already has configurations for 1u through 2.75u for each row in the profile set. Dimensions used in each configuration are shown in the design table (OEM and Cherry were made with the same key widths for each u). Before editing the SLDPRT file, check and see that you have selected the configuration you want.
Thank you for looking! Enjoy.
