The best thing to mass produce?/Other good ways to profit with 50-90 DLs?

[URNOTRONN]

I want to try mass producing something since i only keep losing wls (Had 146 DLs from a thingamabob i got and now my networth is probably around 80-90 DLs..). Soo, what is something i could mass produce or are there any other really good ways for me to earn WLs?

I'd say plumbing blocks since they're used to make science station and they are essential for haloween.

Plumbing isn't expensive, my networth is 70+ dls so it isnt worth for me to do
