Locking key for Ultimaker filament feeder (aka "extruder") by MoonCactus Jun 21, 2012

Description

Tired of the feeder that wants to detach itself from the ultimaker frame each time you push the filament upwards manually?

Scared that it falls off each time you move your box around?

Just stick this thing in the free space above the extruder arms to lock it in place.

OK the best surely would be not to have to push the filament by hand at all, but at least now I do not need both hands to do so :)

Glad you like it. It was also one of the first thing I ever designed :)
This was the 1st thing I printed on my UM! Even before any calibration cubes! I wanted that material feeder secured! Thanks for the model Moon!
Nice one :)
I printed it really fast and touched it before it cooled down enough, so it has a slightly different shape now. But it works still as expected. Thank you!

Instructions

__Update 2013 04 28__: now customizable for any dimension or fine tuning!

Printed with 0.1mm layers, 0.8mm walls and 35% infill (I think less would still be OK).

The thing is completely parametric, you can tweak or derive something better.

You could add and STL for maxy's 'Ultimaker quiet retraction' thingiverse.com/thing:53690
The armHeights should be around 15 and 17.5. But I'm not sure, as I have a slightly modified feeder.
Well, I just made it customizable instead, so you can provide your own dimensions! Use thingiverse.com/apps/customizer/run?thing_id=25436&;code=af91fb3256caaba2f5ac8e446ed20700
Improving on what is already good, it works even better with a less steep slope, slightly thinner:

armHeight1=4.5;
armHeight2=6.5;
Downloaded it. Printed it. Jammed it in. Love it. Thanks! 8-)
