Grand Duke best place to farm gold?

Been playing for 2 years and I feel like I'm going to need a lot of Gold for all the trap and base upgrades I seem to need to buy. My best traps so far are as follows:

Physical: Sandtail Sentinel (6,800, 25) Tactical: Polar Vortex Trap (8,000, 30) Shadow: Interdimensional Crossbow (4,500, 18) Arcane: Arcane Storm Summoner Lighting Rod Trap (5,800, 23) Forgotten: Endless Labyrinth Trap (10,000, 9) Hydro: Steam AugerBot 3000 (7,000, 20) Draconic: Ronza's Flock of Golden Anti-Dragonbots (5,700, 12) Law: Lawful Lifeguard Trap (2,700, 10) Rift: Derelict Airship Trap (2,000, 3)

I have also just gotten a bunch of materials from GWH so i may be able buy better traps.

I don't know what my best base is. The advised to use is the Naughty Printing Press

Current farthest location: Labyrinth, Queso Geyser, Whisker Woods Rift, Furoma Rift

Any advice would be appreciated. Thank you
