“My (10YO) son, Tomo, was very intrigued (with 3D printing) and came up with the idea of making things to sell. I suggested he should start a business and make it happen. We looked online and with almost all of his saved up pocket money he bought an Ender 3 printer for himself. We created some business cards and a Facebook Business page and started to advertise. The response was overwhelming and he has now made close to $1,000 profit from his $250 printer."
