◼ 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.
