Get these set screws to hold the dog-collar and the pommel on. =>https://www.amazon.com/binifiMux-100pcs-Black-Socket-Screws/dp/B07Z8PD8F8/ref=pd_ybh_a_1?_encoding=UTF8&psc=1&refRID=7C14TP0KRAJ3R095T4YR to hold the dog-collar and the pommel on.
Use these tubes for the clear part. => https://www.amazon.com/Bykski-12mm-Rigid-Acrylic-Tube/dp/B07M59M9KZ/ref=pd_ybh_a_1?_encoding=UTF8&psc=1&refRID=Z978E77QQ1TG4VMS98MF

Good luck, and happy printing.
