Another little job that didn’t work.

Those of you that have seen the underside of my bonnet will have seen the tangle of wires behind the bonnet vent, so I thought I’d better (finally) make a cover for them.

I like to print with PLA as it’s easy to work with.  It’s not been a problem in the past using it under the bonnet as all the parts have been supported.   PLA has a glass transition temperature ( tech speak for it goes soft) of 60 degrees, so perhaps this wasn’t the best move in the world. ( under bonnet temp is probably 80 -90 degrees.).

This time I’ve heat treated the bits before I fitted them.  This improves the strength by 40%, the stiffness by 25% and raises the GTT to about 120 degrees, so here’s hoping.

Pic 1). The correct shape.
Pic 2). The shape that the first set ended up.

Not all problems can be solved with gaffer tape.  For those there is WD40.
Not even gaffer tape can fix stupid, but it can mask the sound.

If you can’t buy it or steal it you have to make it.
