Rectangular bases mean cavalry, monsters, chariots, or elite units. They also mean irregular spacing that's a nightmare to measure consistently.
You've been there. Six knights on 50×25mm bases. You spend five minutes arranging them into a perfect 2×3 formation. Then someone asks "are those exactly 25mm apart front-to-back?" and you have to start over.
This system fixes that.
No more measuring between models. No more arguments about legal spacing. No more tipped cavalry during movement.
Pick your formation. We deliver perfect fit. You play.
🎨 See What You're Getting
We've created product images showing different formations and sizes. Due to Shopify's 250-image limit, not every single variation has a technical drawing, but you'll find renders and measurements for the most popular configurations.
How to Use This Listing:
1. Select your size and formation from the dropdown menu
2. Scroll through the listing images to see example trays and dimensions
3. If you need specific measurements, message us – we're happy to help
Most sellers show a generic photo and hope you'll figure it out. We show you actual trays with real dimensions.
💪 What Actually Makes OBS Different
✅ Choose Formation, Not Millimeters
Other sellers give you dimensions and expect you to work it out. We give you ready-made formations:
50×25mm – 2×3 = 2 models wide, 3 ranks deep
60×30mm – 3×2 = 3 models wide, 2 ranks deep
Zero math. Zero mistakes.
🏷️ Every Tray is Labeled Underneath
We print the formation and size directly on the bottom of every tray.
Storage boxes stay organized. No guessing which tray fits which regiment. Pre-game setup is 3x faster.
Competitors don't do this. We do.
📏 Perfect Height Match for Every Base
Most trays use one generic wall height for all bases. OBS doesn't.
We design every tray specifically for its base size. Result: Base tops are flush with tray edges. No ugly lips. No steps. Just clean, professional-looking regiments.
