Holder is made from two parts and additional parts are not needed
Mounting part fits directly to Weber Spirit Grill (probaby to others as well). It has Fish tail mechanism to lock the two pieces together, but there is also possibility to use insert and small bolt as well (4mm holes).
There are two sizes of holder included in MF3 files. Other is larger in diameter, so it fits can with cooler sleeve. The other one fits standard Beer can.
The author marked this model as their own original creation.
