This is a customizable hook designed to snap onto the cross members of IKEA IVAR side units (Like these). The STL file included is for the small hook shown in the pictures; It is perfect for things like keys or cords. See the section below for information on how to customize the model to suite your application.

Customizing

The model is designed in FreeCAD 0.19 and all significant dimensions are defined in the spreadsheet called Params. Notes on what each of the parameters are used for are also included in this spreadsheet.

To customize the model, modify the parameters in the spreadsheet as desired and save it. Then, export an STL for printing by selecting the body called Body and hitting File > Export.

Print Settings

I printed this model with 0.2 mm layer height and 70% infill in PETG. Supports are not needed. Lower infill could be used without any problems.
