Hello all,
"The switch knob is gone, long life the switch knob."
Got a new Frog in the workbench in a fare condition, but needed a lot of cleaning (dust and other unidentified stuff and gore) and?also new knobs on the light and power switch. Which are very hard to get.??So I pulled of the knobs of my other FRG-7's and it turned out there are 2 models of the knobs (left is original, right is the later model).

I liked the original model more so I fired up TinkerCad and started drawing. And the second prototype was spot on.

?Needs a little trimming on the edges, but looks good already and it functional (grey is original knob, white is 3D printed 0.12 layer, 100% infill).

Next steps :
- order roll of red PLA to print the power button.
- print a few more to see if it really is working.
- publish STL file on my website (link will be post here).
When the results are reproducible, I will post the design on my website (and the STL in the file archive of this group).
So when you get your hands on a FRG-7 without a light or power switch knob, you know can print your own.?
