- I saved a Roland digital piano from the landfill by 3D printing a replacement key weight arm.
Huge thanks to Geklatscht for the STL used for this repair:

Excellent video!! You are a fantastic speaker and teacher. Every other word out of your mouth is not “ummm” or “literally”. Very descriptive, easy to follow. Love it!!!
Thx, I had the same issue and it is fixed now! Video was very helpful! I used epoxy glue to repair the broken arm.
Excellent video, very cool on the 3D-printing. These instructions also work on a KR-375 (very different from a KR-370!), though I glued the weight arm and swapped it with F7
How can i find a project to print, or you know some marketplace to buy?I have one kr 570, four keys broken. but here in Brazil didn't find to buy it.
Hope you answer me, thanks
Very cool. I also found a 3D file. However I can’t find one for the black keys. Any idea where
How are they holding up after many months of use? I'm trying to fix a friends piano but I am curious how long the 3D prints are holding up?
I have one of these that I have been meaning to try and fix up for the last few years. It has no less than 30 broken counterweight arms I need to address. Hadn't thought of 3d printing, and I'm wondering if there's an STL also available for the black-key arms which are shaped differently from the white keys'. I do also notice that the thickness of your 3D printed part is different and I'm sure overall it's a little differently weighted itself vs. Roland's factory arms from the late 90s. Does that middle C feel perceptibly different than the keys around it?
If you look really close you can see the replacement key is slightly lower, I probably could have fixed that with a little more padding under that key but I don't notice it all when playing since it is so minor.
@@MerwinMusic Thanks so much for that info, sounds like it is at least worth a try! I see the person who posted the STL for the white keys also hasn't gotten around to the black key hammer apparatus yet. May reach out to them and see if we can collaborate on that! I certainly have enough parts for reference... :)
Me also interested to know how to find an STL for the black keys hammers. On my Roland they get cracked the same as the white ones, all of it across the keybed.
When I need to repair a black key then I will need to make an STL file, right now it isn't a priority for me. Luckily the black key weight arms still seem to be in stock from some places so you can pick one up for a reasonable price.
As I mentioned above, I may try and figure out how to STL up the black key hammers.
I did a search and found those already.
Just write "roland piano hammer" 3D models to print. @@lossfound
