All of the parts can be printed on a stock Ender 3 v2 (i recently upgraded mine with Dragonfly BSM all-metal hotend and a Bondtech CHT 0.6mm nozzle and it printed much better and faster) Most of the parts dont require supports, however the Snail part needs a little supoort in the final straight portion of the tube (the end you connect your hose to)

Recommend mounting to a sturdier bucket. Buckets with thinner walls can deform (depends on the power of your vacuum)
