3D Printed Points

[GAP]

As the project is inside PLA should do the job hopefully, the next thing to do is place all sets in the shed where they are going to be used and expose them to the heat over the summer months.
Outside temps will reach into the 30'sC for the next few months, I suppose I should get a cheap thermometer to measure that the inside temps.

I would think a thermometer check is essential. If it's 30+ outside it will be very much higher than that in a closed shed. It's rare that we get sustained temps that high here, but it gets literally unbearable in our shed and garage when it does.

I think so as well, it will be interesting to see how hot it does actually get.
I do have whirlybirds to take some of the heat out and the roof is about 3M high but it still does get hot, I have had heatshrink shrink in there when it got hot but it was a cheap brand which shrunk extremely fast.
