La 3ème Dimension at Faire Festival 2026

La 3ème Dimension at Faire Festival 2026

From May 28 to 30, 2026, the Faire Festival takes over La Cité — RoseLab in Toulouse. Three days to learn, create, repair and share around making, DIY and the circular economy.

What is the Faire Festival?

The Faire Festival is Toulouse’s major maker gathering — FabLabs, makerspaces, and communities all in one place. The idea: bring together everything related to hands-on and digital fabrication — 3D printing, low-tech, repair, textiles, woodworking, ceramics, solar energy…

Entry is free on Saturday and pay-what-you-wish on the other days.

The programme

  • Thursday May 28 & Friday May 29 (9am–9pm) — workshops, conferences, hackathons, round tables, repair cafés, evening events (fashion show, Maker Comedy Club)
  • Saturday May 30 (10am–7pm) — free open day for the public, families and associations

Over 50 events are planned on Thursday alone.

Where?

La Cité — RoseLab 55 Avenue Louis Bréguet, 31400 Toulouse 5 min from Montaudran station, served by bus lines L8, L9 and 37

La 3ème Dimension will be there

This is exactly the kind of event that fits the spirit of the project: instruments made in Toulouse, 3D printed, designed to be accessible and understandable. We’ll be there to talk, show our work and connect with other makers.

Three instruments will be on show:

Lumi — the educational astronomical telescope, shown for the first time under its new name. You may have known it as ERT — it’s now Lumi.

Smallest — the compact, fast telescope, already well known to regulars.

Picco — the ultra-compact 114/450 Newtonian weighing 1.5 kg, currently in development.

A special edition for the occasion

For the festival, I created a special BHH (Backpack Holder Hook) in the Faire Festival colors. The hook clips under a table, desk or in a tent to keep your bag off the ground — the perfect companion for a maker festival.

The file is free to download on Printables: Backpack Holder Hook x Faire Festival

Printed in PETG or PCTG, no supports needed, strong enough to hold a laptop bag.

If you’re in Toulouse between May 28–30, this is the place to be.

What our customers say

★★★★★

"Happy owner of a Seestar S50, I ordered the accessories that Raphael offers (baffle, dust cover, etc.). All these accessories attach perfectly to the Seestar, without forcing, and hold really well! An essential addition to this little machine. Raphael perfectly masters his designs, the dimensions, and his printing! 100% approved!!"

"I bought these 3 collimation knobs for my Orion XX14i Dobsonian. They replace my old steel screws which, although sold for this purpose, did not have rounded ends and ended up punching the back of my secondary mirror support. The ones from La 3ème dimension are nicely rounded, which makes the adjustment much smoother, without jerks and much more precise. Very satisfied, thank you!"

"I asked Raphael to design several Bahtinov masks in different sizes for me. The work done is impeccable, and done with seriousness and rigor. I am fully satisfied. I will not hesitate, in the future, to call on his expertise."
