A button for MSX keyboard (Yamaha YIS805/YIS503)

thingiverse

This is a prototype for MSX computer keyboards that features an unmarked BS (backspace) button designed to fit Yamaha YIS805, YIS503 or CX5M2 keyboards. The design also includes functional and special keys similar to those used on the YIS805 keyboard (STOP, INS, DEL, SELECT, CLS/HOME). With some scaling adjustments, it can be used as any other similar button on these keyboards. UPDATE (April 21, 2019): I have added a model for a two-component button. The inner part of this button can be printed with a different plastic, such as PLA, which is less fragile than the one used in DLP printers. This allows for flexibility when printing the outer and inner parts separately. To assemble the button, print the outer part on a DLP printer with gaps for lettering using bold font. These gaps should be wide enough to fill manually with UV-hardened material using a syringe. Then, harden the material under a UV lamp from both sides. I have included pictures showing the button before and after filling as well as when completed. Additionally, I have uploaded a three-component button design where text and base can be printed separately on DLP printer using different color plastic. This component is inserted into the outer part of the button and should match perfectly. The inner part remains suitable for printing on an FDM printer. For reference, two examples of 2-component and 3-component buttons are provided. If someone prints them, please share your experience. If you would like to show appreciation for my efforts, consider using the "Tip designer" button found here: https://www.thingiverse.com/Wierzbowsky/designs
