Light 3D mesh - not to heavy to be useful.
Carefully created textures based on 360 degrees photo scan. Flatscans sometimes used If needed.

Model without transparency.

Accurate dimensions, taken from existing, previously bought product -using caliper if possible to measure diameters etc. - no guessing or working with internet-photos only.

Easy to reduce the amount of polygons because of simple and uncollapsed structure:
----spline
+ lathe modifier
+ uvw cylindrical mapping

You can reduce interpolation in spline modifier or/and
reduce number of steps in Lathe modifier depending on your needs/ power of your machine/time left before deadline :).

Only quad polys.
Product bought in 2019.

Enjoy!!
