OO/HO Track Laying Templates & Spacing Tools

OO Gauge Track Laying Radius Templates & Track Spacers

Azuda makes 3D printed OO/HO (16.5mm) track laying templates and spacing tools designed for real modelling use. Shape flexitrack to smooth, accurate curves and hold consistent parallel spacing — without measuring every bend. Integrated handles let you place, slide and reposition each template as you work, and cut-outs let you pin the track lightly so it holds its curve instead of springing back.

Why modellers choose Azuda

Integrated handles

Built-in handles let you grip, slide and reposition each template along the rails — modellers say it’s far easier than flat gauges.

True curves, no spring-back

Form flexitrack to a consistent radius and pin it through the cut-outs so it holds its shape while you fix the trackbed.

Consistent 67mm spacing

Double-track spacing templates hold a reliable parallel gap on straights and through curves, for safe clearance and a tidy layout.

What modellers say

A few words from verified eBay buyers — see all feedback on our eBay shop.

“Unlike other track setting tools, these have handles making moving the pieces along easier. Measurements are in both metric and imperial.”

Verified eBay buyer

“These really help working with flexi track and keep the rails in perfect alignment and prevent overbending and damaging the rails. First class.”

Verified eBay buyer

“Integrated handles make moving around much easier than some. Good value for money — as good if not better than more expensive versions.”

  • Ideal for flexitrack and set-track transitions
  • Works with Code 75 and Code 100 rail
  • Likely compatible with Code 83 (not formally tested)

Frequently asked questions

Which radius do I need?

OO set-track radii run from tighter curves (1st radius, around 371mm) up to broad, realistic main-line curves. Tighter radii suit tabletop layouts, branch lines and sidings; broader radii suit larger boards and express running. Our kits bundle four consecutive radii so you can shape a natural flow from tighter to sweeping curves. Not sure? Message us with your space and we’ll help you choose.

What is 67mm track spacing, and why does it matter?

67mm is a commonly used gap between parallel OO gauge tracks, giving reliable clearance for passing stock — particularly on curves. Keeping the spacing consistent improves both the look of the layout and smooth running. Our spacing templates hold that gap accurately on straights and through bends.

Will they work with my track?

They’re designed for OO/HO gauge (16.5mm) track and are ideal for flexitrack and set-track transitions. They work with Code 75 and Code 100 rail, and are very likely compatible with Code 83 (not formally tested).

What is the 3D printed finish like?

Every item is 3D printed on well-tuned machines and inspected before dispatch. You may occasionally see minor stringing or a small mark from the print brim (used to improve bed adhesion) — it’s purely cosmetic, easily removed, and never affects accuracy or performance.

3D printed quality

All items are 3D printed and inspected before dispatch. Minor cosmetic marks or light stringing may occasionally be present and can be removed if required. This does not affect accuracy or performance.
