Here are the exact measures of the item. If you can 3D print it (white
ABS plastic, otherwise silver), too, please let me know. I would use
PayPal to compensate you for your expenses (material and shipping to
Jamaica, inside a regular envelope with protective bubble foil or foam).

Item dimensions:
total length: 7 cm
total diameter: 6 cm (bottom ring)
angle of torus: 90°
upper ring surface exceeding torus: 0.3 cm (3 mm)
important - upper cylinder edge is rounded (torus)
torus total height: 1 cm
torus total height above ring: 0.6 cm (6 mm)
ring height: 0.4 cm (4 mm)

// If you do the 3D printing, please print in white ABS plastic
(otherwise silver). Thanks.
