I would like to share with you the creation of the Nomai mask, a project inspired by a fantastic concept originally designed for the Prusa XL (thank you Mallow). I designed and adapted this model for my Prusa MK4 printer, and here are the detailed steps for its fabrication.

1. Panel Fabrication

Print the six panel blocks (SW, W, NW, NE, E, SE), then assemble them by gluing them together. Some blocks require supports. To improve adhesion, use triangular \"keys\" that help interlock the pieces.
This step is delicate because the blocks do not provide much grip to ensure proper positioning. I used temporary supports to hold the pieces in place during assembly.

2. Printing the LED Diffusers

Print the LED diffusers (SW, W, NW, NE, E, SE), placing them flat on their widest surface to achieve a clean and uniform finish.

3. Box Fabrication

Print the box with supports, as it has a slight tilt to properly orient the mask.

4. Printing the Mask Centering Piece

This piece should be printed without supports for a better finish.

5. Printing and Assembling the Mask

Print the mask with supports, along with the arms (SW, W, NW, NE, E, SE). Apply a thin layer of glue to the ends of the arms before attaching them to the mask.

6. Soldering the LED Strips

Solder six small LED strips in parallel to the main strip.

7. Attaching the LEDs in the Panel Grooves

Glue the LED strips into the panel grooves. Since the original LED adhesive is not strong enough, use a hot glue gun to secure them properly against the walls.

8. Installing the LEDs for the Eyes

At the end of the main LED strip, solder three mini-strips of 2 LEDs in parallel to illuminate the eyes. To prevent short circuits, apply glue inside the eyes. There is no need to glue the eyes into the mask openings, as they fit securely in place.

9. Final Assembly

Glue the box and the centering piece to the back of the mask.

10. Wall Mounting

Use two nails to securely mount the mask on the wall. And there you have it\u2014your Nomai mask is complete!

Je souhaite partager avec vous la r\u00e9alisation du masque Nomai, un projet inspir\u00e9 d\u2019un superbe concept initialement con\u00e7u pour la Prusa XL. J\u2019ai con\u00e7u et adapt\u00e9 ce mod\u00e8le \u00e0 mon imprimante Prusa MK4 et voici les \u00e9tapes d\u00e9taill\u00e9es pour sa fabrication.

1. Fabrication du panneau

Imprimez les six blocs du panneau (SW, W, NW, NE, E, SE), puis assemblez-les en les collant entre eux. Certains blocs n\u00e9cessitent des supports. Pour faciliter l\u2019adh\u00e9rence de la colle, utilisez des \u00ab cl\u00e9s \u00bb en forme de triangle qui permettent d\u2019embo\u00eeter les pi\u00e8ces.

Cette \u00e9tape est d\u00e9licate, car les blocs n\u2019offrent pas beaucoup de prise pour garantir une bonne position. J\u2019ai utilis\u00e9 des supports temporaires pour maintenir les pi\u00e8ces en place durant l\u2019assemblage.

2. Impression des diffuseurs LED

Imprimez les diffuseurs LED (SW, W, NW, NE, E, SE) en les positionnant \u00e0 plat sur leur face la plus large afin d\u2019obtenir une finition propre et homog\u00e8ne.

3. Fabrication de la bo\u00eete

Imprimez la bo\u00eete avec des supports, car elle pr\u00e9sente une l\u00e9g\u00e8re inclinaison permettant d\u2019orienter correctement le masque.

4. Impression de la pi\u00e8ce de centrage du masque

Cette pi\u00e8ce s\u2019imprime sans support pour un meilleur rendu

5. Impression et assemblage du masque

Imprimez le masque avec des supports, ainsi que les bras (SW, W, NW, NE, E, SE) sans support. Appliquez une fine couche de colle sur l\u2019extr\u00e9mit\u00e9 des bras avant de les fixer au masque.

6. Soudure des bandes LED

Soudez six petites bandes LED en parall\u00e8le sur la bande principale.

7. Fixation des LED dans les gorges du panneau

Collez les bandes LED dans les gorges du panneau. Comme l\u2019adh\u00e9sif d\u2019origine des LED n\u2019est pas assez puissant, utilisez un pistolet \u00e0 colle pour bien les fixer contre les parois.

8. Installation des LED pour les yeux

\u00c0 la fin de la bande LED principale, soudez trois mini-bandes de 2 LED en parall\u00e8le pour illuminer les yeux. Pour \u00e9viter les faux contacts, appliquez de la colle \u00e0 l\u2019int\u00e9rieur des yeux. Il n\u2019est pas n\u00e9cessaire de coller les yeux dans les orifices du masque, ils tiennent bien en place.

9. Assemblage final

Collez la bo\u00eete et la pi\u00e8ce de centrage \u00e0 l\u2019arri\u00e8re du masque.

10. Fixation au mur

Utilisez deux clous pour fixer solidement le masque au mur. Et voil\u00e0, votre masque Nomai est termin\u00e9 !
