This made us want to free the imagination of these children. This is how Lunii and its My Fabulous Storyteller came into being in 2014, offering children an audio storyteller that lets them create their own stories but also listen to their favourite tales in an independent and safe way.<\/p>\n\n\n\n<p>Thomas Krinbarg is one of the four founders of Lunii. He mainly works on the design and conception of My Fabulous Storyteller, the brand\u2019s flagship product. This audio storyteller was the first of its kind launched on the market and is based on a simple principle: the child turns on the box and chooses the four defining elements of their story (universe, main character, secondary character, and object). These four choices determine which of the 48 pre-recorded stories will be told. In addition to these stories, Lunii also offers classic childhood stories.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"header-0\"><strong>The silicone shell: a new storyteller accessory<\/strong><\/h2>\n\n\n\n<p>Given the success of My Fabulous Storyteller, the Lunii team decided to diversify with the launch of a publishing house, stories adapted to different ages, headphones, and more recently a silicone shell (\u201cLa Coque Odile\u201d) designed to protect the storyteller. \u201c<em>You shouldn\u2019t underestimate a child or their parents<\/em>,\u201d Krinbarg jokes.<\/p>\n\n\n\n<p>Although the idea of making a shell came to him in 2021, it wasn\u2019t until the end of 2022 that the co-founder seriously tackled this project. He first designed what he called a \u201cbrick\u201d big enough for the storyteller. Then came the question of the manufacturing process, the material, and the shore hardness for the shell, which he wanted to be both flexible and durable.&nbsp;<\/p>\n\n\n\n<p>Krinbarg quickly finalised his 3D file and started looking for a new partner to produce a POC (\u201cproof of concept\u201d) to present to the team, as he wasn\u2019t happy with the first 3D printed test.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2023\/07\/cad-design-shell-lunii-prototype.png\" alt=\"3D model of the silicone shell\" class=\"wp-image-112079\"\/><figcaption class=\"wp-element-caption\"><em>3D model of the silicone shell<\/em><\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"header-1\"><strong>Xometry\u2019s technical advice and production capabilities<\/strong><\/h2>\n\n\n\n<p>While doing some research on the Internet, Krinbarg discovered Xometry and requested a quote for the shell from the 3D design he had imported onto the platform. He was immediately contacted by Lison, Key Account Manager for France, who helped him choose the most suitable manufacturing technology.&nbsp;<\/p>\n\n\n\n<p>She suggested using vacuum casting to produce the prototype instead of 3D printing. This process is ideal for producing flexible parts that are extremely close to the output in mass production in terms of mechanics and aesthetics.&nbsp;<em>\u201cInstead of letting me simply complete my order as it was, Lison contacted me and suggested an alternative solution more suited to my project,\u201d<\/em>&nbsp; says Krinbarg.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2023\/07\/prototype-shell-lunii-1440x1080.jpg\" alt=\"Prototype of the shell with a shore hardness of 40 made using vacuum casting with Xometry\" class=\"wp-image-112057\"\/><figcaption class=\"wp-element-caption\"><em>Prototype of the shell with a shore hardness of 40 made using vacuum casting with Xometry<\/em><\/figcaption><\/figure>\n\n\n\n<p>They discussed the choice of material and the shore hardness that could be suitable for the product and lastly chose to make the shell out of a rubber-like material with three shore A hardnesses (40\/50\/60) to compare the final result.&nbsp;<em>\u201cIn some places, the shell is quite thin and if the shore is too low, the material doesn\u2019t perform well enough and there was a risk of having a strip that was too soft.\u201d<\/em><\/p>\n\n\n\n<p>To give their product an ideal look and feel, Krinbarg adds an SPI-C1 surface finish that lightly polishes the part to give it a pleasant feel.<\/p>\n\n\n\n<p>\u201c<em>It was fast and competitively priced \u2013 exactly what I wanted,<\/em>\u201d says Krinbarg. He also appreciated how easy it was to understand things he wasn\u2019t particularly familiar with thanks to Xometry\u2019s expert guidance. This POC allowed him to validate the project within the team and to launch serial production of the brand new shell.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2023\/07\/blue-shell-lunii-1440x907.png\" alt=\"\" class=\"wp-image-112123\"\/><figcaption class=\"wp-element-caption\"><em>The final version of the blue shell for My Fabulous Storyteller<\/em><\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"header-2\"><strong>The story continues<\/strong><\/h2>\n\n\n\n<p>Launched in summer 2023, the shell will join the panoply of accessories now available.
