Nucleus 13inch beaker bong accessories

This is based off of https://dankstop.com/products/nucleus-silicone-beaker-bong
I have made 3 parts for it
1. Ice catcher - pressure fit, it is 2mm bigger than the tube so it wont move with ice on it
2. Top cap - airtight seal
3. Downstem cap - airtight seal

I also upgraded the 3 inch downstem for $6 with an elev8 silicone downstem
