Wow, a really great model. The assembly is very well thought out ... My 4‑year‑old is thrilled: she immediately understood how the clock works and now tells us exactly what is being shown. Thanks!

I built both Remindi clocks. The build is very well documented, and when I had questions I received very fast help by email. I especially liked the KidsClock: my 4‑year‑old grandson has a lot of fun with it and every time he visits he explains the symbols and what they mean. Thank you, Remindi, for this great project.

I have built this clock for my 2 years old and he loves it ! He understands every light and is excited to tell us what each one means. The design is really nice, the web interface to control it is intuitive and the whole thing is really well designed. I highly recommend it ! All in all, it's a great make, well executed and the creator deserves praise for his involvement !

What about the wooden frame?
For my version, I built a frame from 12 mm oak laminated wood. I cut 4 wooden strips (4 cm × 20 cm) at 45° mitre angles, glued them together, sanded with 180 grit, and finished with wax. The printed Kids_Front fits perfectly into the 176 × 176 mm inner space.
If desired, I can provide a separate tutorial or video for this wooden frame.
Alternatively, you can simply print the provided Case file and use it as the frame.
