Product overview

Set a miniature on its 25mm round base into one of these converters and it reads as a 32mm round base — no rebasing, no glue, no magnets, nothing removed from the model. It suits rank-and-file infantry moving up to the larger round size used for bigger troopers, and it is fully reversible: lift the model out and the original base is untouched. The converters are part of the Open Basing System and stack with the range’s own bases, trays and other converters.

No glue, magnets or rebasing — removable and reusable across the collection.
Injection-moulded ABS with a secure hold around the existing base.
Textured top surface matches the rest of the range for a consistent look.
Works with Open Basing System bases, movement trays and other converters.
Available in packs from 1 to 100.

Compatible with popular tabletop miniatures; not affiliated with, endorsed by or produced by Games Workshop.

Notes · Q & A

Can a converter change my base footprint without rebasing?

OBS converters are designed to adapt an existing base where the selected conversion route fits that original footprint. Fit is route-specific, so confirm the selected option and technical drawing before ordering. Check Technical Specifications where added height matters.

How do I choose the correct converter?

Start with the footprint you already have, then select the target footprint you need. Compare both the accepted inner fit and the outer footprint with the technical drawing; matching nominal labels alone is not enough.

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.

1x Base extender for my old gk character

The base extender came really fast, and was the right size so I can't really as for much more. The purchase email was great too, made me laugh!

The future is now old man

Like the last reviewer, I didn't want to rebase my night lords. This army is older than my 5th grader.
But these made it a dream. Seamlessly integrates with what I've got and just needs a little terrain extension to be invisible.

Best Base Adaptors

I really didn't want to have to do it. I had based my Orks back in 5th Edition 2012.

Well rules change and I needed to be legit to attend the Warhammer Open 2026 in Tacoma, WA. So I started looking at my options. Removeing the model wasn't possible on many of the model as I used slotted bases superglued too tight. I didn't want those 3D printed rings those look cheap.

These base adaptors I got to say look great. The plastic is quality. A little taller than the standard base size but it's okay. Fist tight but not to tight. I used GW plastic go and finished 78 orks in about an hour.

I will be ordering more because I don't have enough to update all may Space Marines.
