Here’s a video demonstrating the glove manufacture theory.

One of the main problems with this theory is that there were easier and cheaper ways to make gloves.

About a hundred of these dodecahedra have been found from Wales to Hungary and Spain and to the east of Italy, with most found in Germany and France. Ranging from 4 to 11 centimetres (1.6 to 4.3 in) in size, they also vary in terms of textures. Most are made of bronze but some are made of stone.
Use as a measuring instrument of any kind seems improbable since the dodacahedrons were not standardised and come in many sizes and arrangements of their openings.
… Smaller dodecahedra with the same features (holes and knobs) and made from gold have been found in South-East Asia. They have been used for decorative purposes and the earliest items appear to be from the Roman epoch.

Where they are found, the archaeological context, may be a clue. Thirteen were found near military sites.

The sites are very diverse.

Dodecahedrons are amongst others found in military camps (13), graves (3), near a sanctuary (1), in treasures (2) and as a river discovery (3).

As astronomical measuring devices, they may have been used like this:

Interestingly enough, dodecahedra have been around since before Roman times and the Romans could have learned of these from the Etruscans; Etruscan dodecahedron from Monte Loffa:
