Even if something is manufactured magically, it's Muggle tech if it was designed by Muggles and works without magic once created.
A huge amount of the ordinary things we see in the movies are technology. Old and familiar technology, but if you were sent back in time to the stone age, or stranded on a desert island, could you make them yourself in under an hour? (You don't even have to draw the line there, but using a rock as a tool probably doesn't count as a technology.)
You might not think of your shoes as "technology", but someone invented them. Modern sneakers are made out of a lot of different modern materials to achieve light weight, good padding, and good grip on the soles. Not to mention the exact shape to provide support for the foot. All this stuff is non-trivial, and isn't something you'd just know how to design well if you didn't have a reference while you were creating footwear by magic.
A wizard would probably have to put a lot more effort into making some of these things that were permanently enchanted to provide these qualities without modern Muggle designs and materials.
- Clothing: (woven / knit fabrics and textiles), buttons, (zippers?). Insulating fabrics.
- Shoes made of modern materials, e.g. rubber soles. Modern leather shoes are non-trivial pieces of design, too, even if the material they're made of is an ancient tech.
- Glass windows, doors with hinges, doorknobs, locks. (Many structures as a whole seem to be magic, otherwise they'd fall down, so I'm not including house / castle construction techniques. But clearly wizard housing is based on Muggle design ideas.)
- Indoor plumbing / taps / flush toilets / ceramic fixtures.
- Wooden & upholstered furniture (chairs, tables), beds
- Pottery: plates, bowls, cups.
- Bookbinding: The movies definitely depict modern-style books. This kind of binding definitely post-dates the earliest wizards.
- Metal utensils, like cutlery (knives and forks).
- Metal weapons: Bellatrix has a dagger/knife in movie 7
- Candles / lamps. (Not sure whether lighting is usually pure Muggle and actually burning fuel, or whether it's more usually magic.)
- Optics: glasses. Perhaps magical optics (like Mad-Eye's eye) have some components that take advantage of some non-magical physics.
- Boats
- The wheel, seen in the movies on horse-drawn carriages, if we want to get really old-tech
IDK how long the Wizarding community has existed hidden from the mainstream, but many of these things were developed after that split. And definitely what's shown in the movies is a modern version of every technology, so wizards keep checking in on Muggle tech to update their designs, or else wizards simply buy Muggle-manufactured goods.
If you expand the criteria to include magic versions of Muggle tech, then most common objects are recognizable as a "wizard version" of a Muggle design, serving the same purpose in a similar way. (e.g. photographs, marauder's map, knight bus).
A wand is one of the few physical objects common in the wizarding world that isn't obviously inspired or derived from a Muggle object, but even wands are made of wood in a way that could be done non-magically with woodworking techniques. (There are many un-common magic objects that are uniquely magical, like a pensieve, but most wizards don't have one.)
Flying brooms have the same shape as a Muggle object, but are clearly a separate technology altogether. Similarly, many wizard travel and long-distance-communication "technologies" have no Muggle inspiration.
