A reverse coupling ring to do that kind of work more conveniently should only run you a few dollars (like this). You may also need a step up/down ring if you can’t find one with the correct thread sizes, though.
Since I think you shoot Nikon, the final thing you might want is a BR-3 Adapter, that lets you mount 52mm filters/hoods on a reversed Nikon lens. Those are a bit pricier, but I got a used on on Ebay for about $20.
Of course, that setup isn’t nearly as convenient as a macro lens, but it does allow for magnification well beyond 1:1
