Mini introduction

Here’s a mini-interview we shot for Climb Fit Sydney.

Gives you a super quick look at who we are, what we do and why we do it!

Scouting new routes

Our first replica route was Lindfields Rock’s, The Blank Wall. It’s a balancy slab climb with lots of pockets.

For our next replica routes we’re looking to add some variety to the mix. So we’ve got overhangs and roofs in our sites!

Here’s a quick look at our day out, hunting for the perfect route.

Let us know in the comments if you know an Aussie classic you want replicated!

Holds on the wall! 

We've started testing our full scale prototypes!

We mounted a replica of Lindfield Rock's the Blank Wall. It was a bit uncanny climbing this one in a gym.

Rebuilding outdoor holds

Our holds are shaped by nature, but they aren't rebuilt by it.

To build our replica climbing holds we've had to combine some new and conventional production methods.

Take a sneak peak at some of these steps in this video.

 The Blank Wall

Lindfield Rocks is a popular bouldering spot in North Sydney. It’s got mostly vertical climbs and the locals have millions of variations of each route.

We’ve had a bunch of fun climbing sessions here. Our first full scale prototype route was sourced from here, The Blank Wall.

It’s a slabby climb, with some balancy moves and small pockets. If you’re keen to see some samples or the full replica in your gym let us know!


Here's an example of one of our first climbing hold models, from Queens Park Sydney. This is the raw mesh geometry we get from our 3D scanning.

We then digitally sculpt these models into climbing holds that can be mounted in gyms.

Here’s an example of one of our first cliff models, from Queens Park Sydney.

We use these models to obtain accurate positions for our holds, so we can mount them in the exact same place indoors.

Home woody

Every climber would love to have a climbing wall at home.

Twin Climbs also needed somewhere to safely and quickly test our prototypes, before trialing them at gyms. A good enough excuse for us.

So, after many late night discussions and some trips to the hardware store we were able to finish our very own home woody!


Bake for 60 minutes at 60°C.

After our climbing holds finish printing we cure them in with ultra-violet light and heat. This brings out the materials maximum strength, which is almost twice as high as some other climbing hold plastics. It also makes for a pretty good light show.

Printing in layers as thin as a human hair lets us recreate ultra fine features and textures.

SLA printing uses photosensitive resin and a UV laser to build parts from a pool of resin.
