◼ 75mm squares - a custom size for hobbyists who need something between standard sizes. Great for larger scenic bases, multi-model dioramas, and projects where you want that classic square aesthetic.
🔓 Open Basing System (OBS)
75mm square isn't a standard size in any game system - and that's the point. OBS gives you sizes that hobbyists actually ask for, not just what corporations decide to sell. Custom projects, display pieces, your rules.
🎨 Perfect For
💡 When you need a square format but standard sizes don't fit your vision. Your project, your choice.
🧪 Why PETG?
Impact resistant
Won't warp
Primer & paint
CA & plastic cement
⚠️ About FDM Printing
Layer lines: FDM printing builds objects layer by layer, so you may see subtle horizontal lines on the surface. These are completely normal and largely disappear after priming.
💡 For glass-smooth display pieces, resin might suit you better. For gaming armies, these work brilliantly.
🛠️ Prep Tips
- Wash with soap & water before priming
- Prime with Vallejo, Army Painter, or Citadel spray
- Sand with 400-600 grit if ultra-smooth needed
- Pin heavier metal/resin models - PETG drills cleanly
❓ FAQ
Is 75mm square a standard size in any game?
No - it's a custom OBS size. Perfect for hobbyists who need something different from the usual corporate options.
Can I drill pin holes for heavy models?
Yes, PETG drills cleanly. Use a pin vice and go slowly - essential for heavier metal or resin models.
Do I need to prime them?
Highly recommended. Acrylic paint on unprimed PETG can scratch off.

03 OBS FAQs
Can I add magnets underneath OBS bases?
Check the selected option's underside opening and available underside depth in Technical Specifications before choosing magnets. Magnet fit depends on the actual cavity dimensions and the magnet you plan to use, so it should not be assumed to be the same across every base.
How do I choose the right base size?
Start with the base footprint required for your model or game, then confirm the selected option against the Technical Specifications. If you are replacing an existing base, measure it carefully and compare its physical footprint before ordering.
How should I use the technical drawing?
Choose your option first, then use the technical drawing and Technical Specifications to check the physical dimensions of the product. When matching an existing part or accessory, use the drawing rather than relying on the product name alone.
Can I rely on the nominal size alone?
No. Products with similar nominal sizes can have different physical dimensions or fit differently across brands and systems. Check the technical drawing, specifications and any product-specific compatibility note before ordering.
