Inspired by [king chess piece from Creative-Prints](https://www.printables.com/model/582262-kingkonig-chess) (partially traced the original model for proportions), this is a king chess piece to use as the control stick attachment of electric wheelchairs (the metal pin measures 6.15 mm diameter). It is designed to print well in TPU, providing good haptics with a rounded top part and a cross at the top that is printable with low number of perimeters and infill (to not be an injury risk).
I have also uploaded the tool bodies I used to generate the hole (in the f3d file), so that if you want to stick-ify a different model, you can use them to make the cut. Please note that different electric wheelchair models may have different pin diameters, so check it beforehand and scale if required.
To slice I highly recommend taking the settings from the 3mf file, specifically 3 perimeters, 40% infill (cubic) default, with 60% infill for the upper portion of the thinner part, and 2 perimeters 15% gyroid infill for the cross itself. To ensure that the cross is not printed solid, you may need to reduce the “solid infill threshold” to 20 mm^2.
