Help!! Indicators!!!

[zg862]

Hi there.

 

I'm drawing up a replacement part for the bit of the indicator stalk that breaks and stops the cancelling working but I'm stuck. I don't have the little wings that break off near the pivot, so I don't know what I'm trying to replicate (see the red areas in the attached drawing).

 

Does anyone have one in bits that they could photograph for me please?

 

Incidentally, my first test print seems pretty good (even in PLA, it's stronger than I expected). If anyone is interested in the .stl file, let me know.

 

Many thanks,

Z

2nd prototype building on the printer now. Roughly 2.5 hours estimated print time. Let's see how this one turns out...

Hmm.
Partial success. Here's the original (broken part) followed by my various prints to date.


1st was OK but was missing bits and had inaccuracies.
2nd did a "ball of wool" failure.
3rd had bed adherence problems and did a blob.
4th came out 95% OK but failed where the factory ones do when I tried to fit the "W" spring. (Broken tab to left of print)

I need to figure out how it is supposed to work before I can set about beefing it up at all. I may also need to change the layer orientation to give more strength.
It's progress, but not there yet.

Any insight/informed speculation into how the tabs actually cancel the indication would be much appreciated.

PS/ The bulk of the printed part seems to be dimensionally within tolerance. The stalk fits, interlock parts fit, roll pin fits etc.
