Fisher Price Cash Register Coins - Model #B926A

thingiverse

I wanted a more authentic and precise representation of the Fisher Price Cash Register coins (model #B926A) and was able to use one of the original coins as a starting point. I'd love it if someone could add bumps to the inside coin surface. Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: Fast Infill: Light Post-Printing How I Designed This The Story of How My in-laws had an old vintage Fisher Price Cash Register sitting in their basement, and my 5 and 7-year-old immediately took to it. The problem was that there were only two coins left. I was already thinking about setting up a coin-bank for the 3D printer at school, so I asked if she might lend me the toy. She gave it to me instead. I got home and found this helpful resource: http://www.thisoldtoy.com/l_fp_set/toy-pages/900-999/926-cashregister.html. From here, I was able to back calculate exact dimensions for the coins and make a reasonable facsimile in Tinkercad that looked and felt more consistent with the original toy than any design found on Thingiverse. I wanted to ensure the lines were smooth, so I chose a three-piece design that would snap together at the end. The first prototype came out really well, but wasn't aesthetically perfect, so I increased the font slightly and made the middle notch of the ring more pronounced. I haven't tried 10s and 5s yet (only built 25 before writing this up) but think it should all work well. All in all - for all three coins it took about 3 hours to create start to finish, and another 5 hours of printing to get them into the real-world!
