Mounting Vibration Motors. Vibration motors often sit on/within an enclosure or directly on PCBs. You can easily 3D print an enclosure to house the vibration motor and to mount it. If mounting onto a PCB, there are often options for soldering via through-hole pins. In the case of Coin and LRAs, you can just use the adhesive backing.
