Stylus Guards are a necessary evil, but detachable ones can be avoided.
If it is the most importance the Cartridge is protected and ultimately the Cantilever, a Simple Cover can be made that sits on the Plinth and covers over the end of the Wand, and Headshell.
It might not be an attractive device as a first design, but the security it offers to the Cartridge and fragile parts is the first consideration, ease of placing/removing is the second consideration, stability in use is the third consideration.
Once a device is in place and fit for purpose, a design and aesthetic can then be thought out for final version.
As already said, an Acrylic Lid for the TT, does alleviate 99% of the concerns that can develop.
The Link shows a device that can offer much of what is able to be achieved from a Acrylic Lid. These devices can be found in different colours and prices.
