The universal difficulty of learning a second language is the fact that students' ears, mouth, eyes, hands and mind are not immersed in the environment. When they don't have the chance to use what they learn soon enough, students quickly forget what they learned. To solve the problem of lacking the environment and chances of using what is learned when learning a second language, I designed a watch in my mind (seond, hand drawn picture shown here) to create chances for anyone who is learning a second language to review and use the words they learned quickly, frequently, and stylishly. I was able to use a pendant to make something very close to what I have in mind and have all the functions I want in about 30 minutes.
I believe 3D printer can execute my design exactly which I don't have access to. I used what is available to come up with a bracelet which creates fun environment and chances to use what is leanred when someone is learning a second language, such as Chinese.
Below are what I used, steps taken, and resultant first master piece.
1 Hinged oval pendant with latch hook approximately 0.875 in by 1.125 in
1 Matching necklace chain
1 Small lobster clasp
1 Small jump ring
1 Solder iron kit
1 Chain nose pliers
1 Round nose pliers

Step 1: Have a pendant!
I have a modest ambition for my ABC child (American Born Chinese) to learn Chinese as second language: One word a day. To solve the problem that she doesn't have much chance to use what she learns everyday, I designed a watch in my mind which has hinge and latch hook allowing changing the word easily everyday. I strategically pick a word for her to learn everyday. She spends about 5 minutes writing and saying the word. Then she can show and tell about the watch in school, or tell what the word is when asked, look at the word at any time during the day. Thus, she has repeated chances to review what she learned and making it stay.
I believe a 3D printer can make this watch. But I don't have one. I had a pendant with hinge and latch hook, a bail (attached metal loop)which I had picked up a long time ago. The first thing is to solder another loop on the opposite end so it can be worn on wrist (I always feel a chain around children's neck is a safety hazard, so making a pendant necklace is not an option). In fact, that's almost the only thing to do.
