new to prop building need some advice on my kit

just starting my venture into doing some personal builds just wondering what tools and such i should have on hand and what most people use on a daily basis while making your own . ( mainly gonna be working with plastic or resins)

i have a Praxxon Rotatry tool and most hand tools imaginable what else should i be looking for?

Welcome,
The main tools you'll need for a resin kit in my opinion are... Xacto Knife (or Equivalent), needle files (different shapes and sizes), standard files, a lot of sandpaper in different coarseness, optional... clamps, Dremel Tool, tweezers, various tapes, and an endless supply of patience.

I could use some of that patience stuff. were do I buy It...
