Two routes to a fully populated table
Most tables have the same problem: the DM has a beautiful battlemap, the players have heroic figures painted by hand or printed once and treasured, and the eight goblins ambushing them are represented by Skittles or pen caps. Printable minis fix this without committing your whole evening to a paint station.
The paper packs are the fastest route to a fully populated encounter. Print on cardstock, score the fold, glue the base, done. A pack of fifteen goblins takes maybe twenty minutes from PDF to table. They are not collector pieces, but they are unmistakably "that goblin" rather than a generic placeholder, and they survive a campaign of in-person sessions if you treat them gently.
The STL packs are the long-game investment. If you have access to a resin or FDM printer, you can print a custom encounter for the cost of a coil of filament and an evening's slicing. The files are scaled correctly out of the box for 5e size categories, with bases sized for the standard tray inserts most VTTs and tabletop games use.
Why scale matters more than you think
A miniature that is the wrong size makes positioning weird. A "Huge" creature that fits comfortably in a 1-inch square is just a Medium creature with a fancy paint job, and your players will treat it that way. They will not respect its reach, they will misjudge its threat zone, and the combat will feel scaled down even though the math says otherwise.
The minis here ship at the right scale for the size category listed in the stat block. A young red dragon fits a 15 ft × 15 ft footprint on a 1-inch grid (so a 75 mm × 75 mm base). It looms over the party correctly, which is half the encounter design. Players treat it like the threat it is the moment they see it on the map.
Pairing minis with battlemaps
The cleanest tabletop setup is a printed battlemap, gridded at 1 inch per square, with the right minis on top of it. The grid overlay tool on this site handles the gridding part. Pair it with a MakeMythic battlemap, place the printable minis from these packs, and you have a session that visually does most of the storytelling for you.
For VTT-only tables, the same logic applies in reverse: build a battlemap export at 70 px per square (Roll20 default), use the token maker to crop matching tokens, and run the same encounter you would in person. The shop's printable mini packs are designed to look good either way; the source art works on a printed paper base or a digital token.
