Internal spacer for a Jaymar 25-key toy piano

prusaprinters

My spouse has an old Jaymar 25-key toy piano (it reads “US Patent 2,641,135” below the company name on the front), and a number of the keys were dead - no travel, and therefore no note played if you pressed them.I opened up the top of the piano to find that an upper retention bar inside had bowed over time, and some of the keys had slipped out of place and become jammed.  A quick fix was to design this little spacer.  It slides over the top of the retention bar (you need to apply a little pressure, it's a tight fit), and has two legs that pass around one tone bar without making contact and brace against the rear panel of the piano.  Once the retention bar is correctly positioned, all the keys can be slid back underneath and will move correctly.The piano is fully playable again.  I have no idea whether anyone else in the world will ever have this problem, but if you do, here's a fix.
