3D model description

Jonction-P is a simple but strong plastic connector allowing you to build custom and modular furniture, using rectangular wood sticks. The square version of this model, using a wooden profile of 17mm x17mm, found at Leroy Merlin, in Paris, has the advantage of being reversible. The same component can be used to build a table, a shelf or even architectural structures (if you are motivated enough).

Make sure to watch the VIDEO:

To build your own Jonction-P furniture, using the provided model, you will need 17mmx17mm (18x18) wood sticks. Here, we used the affordable pine wood available at this dimension in our local hardware store, Leroy Merlin. First, sketch the dimensions of the furniture you want to make and cut the wood sticks accordingly. You need four wood parts and four connectors to complete a frame. To fill this frame, you\\\\'ll need to cut a wooden surface out of PLYWOOD. To get a better looking result, cut the edges and the corners at 45 degrees, the plank will fit perfectly in the frame's hole.

You need 16 wood screws to fix a frame and 4 smaller ones to fix the Plywood. Screw tight, otherwise the structure will be weak. Repeat for the needed amount of surfaces. Tip : the more boards, your shelf has, the strongest it will be.

Once done, slide the furniture's legs at the wanted height and screw on place with the remaining holes in the Jonction-P connector.

Take a look at the video to help you :

If the final structure lack strength, do not hesitate to use the connector's remaining holes to screw the furniture to the wall. Also, the remaining holes can be used to attach metal cables to create a X at the back of the structure, giving it a better triangulation. I also provided a small plastic part (Contreventement) that can be used to assemble several Jonction-P modules together.

Be creative!

Looks like .scad files were never made public (I searched the interwebs up and down). Someone made a 9mm, for mini-furniture, at Thingiverse but everything else is 27mm. Brazilian Leroy Merlin doesn't have 27mm pieces, lol. I'll try scaling it up, should work...

attention car il y a une erreur dans la description ... ce sont des 27x27 ... et pas 17 ... :(
je suis bon pour aller racheter tout le bois du coup :/


Je trouve votre système très ingénieux et j'aimerais me faire une étagère sur mesure. Cependant, je me suis rendu compte que les calculs pouvaient être compliqués en fonction des dimensions maximales du meuble, de la taille des tasseaux et des tablettes trouvés dans le commerce, du nombre d'étages souhaité et de leurs hauteur.

Pouvez-vous communiquer les calculs, car j'aimerais également développer un site permettant à n'importe qui de pouvoir réaliser ces calculs facilement.
Afin d'acheter le minimum de matériaux, et de savoir ou découper le bois.



Could you provide the parametric file.
I need to make it for 17mm*17mm from Leroy Merlin ;-)

Thanks on beforehand

There was no parametric file attached to this... where can i find it?

Could be add the parametric file?
I need edit some dimensions.

Bonjour et merci pour le partage, par contre le fichier paramétrique n'y est pas ! possible de l'avoir (fusion360) ? merci

Que conseillez vous comme matériaux ? Le PLA est il suffisant ?
