Spanish Football League trophy - customizable

This is a replica of the Spanish Football League trophy, with optional customizable text engraved on the base.

I made this in response to a request from Rómax posted on the 3Drequests subreddit.

Customizing

Customizing this model requires OpenSCAD more recent than the 2021.01 release.

The most common customization may be to make this trophy bigger than the 60 mm cup diameter provided with the model files here. The diameter and rim thickness may be customized, as well as the number of hexagonal bumps around the rim. All other cup and base dimensions are based on the rim diameter.

For large trophies, or for printing in different colors, you can set the display parameter to render the base and cup separately. For small sizes like the one provided, you can have different colors by setting your slicer to perform a color change after the top layer of the base pedestal.

The proportion of the nameplate-area of the base can be adjusted by the pedestalshrink parameter to make more room for large-size text; the total height of the base is not changed. Other adjustable parameters include the font, font size, and font spacing.

Print settings

Printer: Prusa MK3S

Resolution:  0.2 mm layers, 0.4 mm nozzle

Notes:

• Supports: not required, but you can use organic/tree supports for the top of the handles.
• Speed: If not using supports, slow down your bridge perimeter speed to 15 mm/sec because there are two rather long bridges at the top of the handles.
• Infill: I recommend adaptive cubic 20% for the interior infill and octagram spiral for the top and bottom surface infill.
• Other: In PrusaSlicer, make sure the experimental "extra perimeters on overhangs" setting is disabled.

How I designed this

This was made by upoading the reference profile image into the desmos.io bezier curve calculator to get bezier control points for the cup and handle curves, and approximate the curves on the pedestal base. The interior profile was guessed to be roughly parallel to the exterior curve. With the bezier control points, a polygon profile can be generated in OpenSCAD to pass into rotate_extrude() (for the cup and base) and extrude() (for the handles).

When engraving the text around the base, I account for the proportional widths of each character using the new textmetrics() functionality of OpenSCAD, converting the width to an angular arc length for subtracting characters from the cylindrical surface of the base. The carve-out shape in the back of each chracter is made with the new roof() operation.
