For the Jar itself, you will also need :

• 110mm PVC Sleeve : https://www.bassin-baignade.eu/en/manchons-pvc/199-pvc-sleeve-110-mm.html
• closed 110mm PVC cap for Sleeve : https://www.amazon.fr/gp/product/B075HWQLLD/ref=ox_sc_saved_image_2?smid=A1X6FK5RDHNB96&psc=1
• open 110mm PVC cap for Sleeve : https://www.amazon.fr/gp/product/B019AXNA5O/ref=ox_sc_saved_image_3?smid=&psc=1

If you choose to use pads, you will also need some rubber pads to put under the pad object in order to tamper vibrations.
