TRUE 60mm Round Bases – PETG 3D Printed | Hobby Heaven UK

Read Before Buying

These are TRUE 60mm bases – exactly 60mm diameter.

Movement trays designed for 63mm
Base toppers/inserts for “60mm” (actually 63mm)
Existing GW-standard armies

Need GW-compatible 63mm? These are NOT for you.

Open Basing System (OBS)

GW calls them “60mm” but they’re 63mm. The industry followed. We made actual 60mm for hobbyists who need real dimensions – not “close enough.”

Your models. Your army. Your choice.

Who Needs TRUE 60mm?

Scale modellers Historical wargamers Precision projects Custom trays Dioramas CAD/laser cut Non-GW systems

If you’re designing custom movement trays or laser-cut MDF with metric dimensions – these will actually fit a 60mm hole.

Why PETG?

Impact resistant Heat Safe
Won’t warp Paintable

CA & plastic cement

About FDM Printing

Seams: FDM prints have a visible “Z-seam” – a thin vertical line on the base edge. This is not a defect, it’s normal.

Layer lines: Subtle horizontal lines may be visible. These largely disappear after priming.

For glass-smooth display pieces, resin might suit you better. For gaming, 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
Base with texture paste, sand, tufts – all adhere well

FAQ

Will these fit GW movement trays?

No. GW trays are for 63mm. These will be loose. If you need GW compatibility, these are not for you.

Why do GW bases say “60mm” if they’re 63mm?

GW always called them 60mm, the industry followed. The actual measurement is 63mm. We call ours “TRUE 60mm” to be clear.

Do you sell 63mm (GW standard) too?

Yes! Check our shop for the full OBS range including 63mm GW-compatible bases.

Do I need to prime them?

Highly recommended. Acrylic paint on unprimed PETG can scratch off.
