That's a lot of fiddly trimming to do, will it not print without the rim?
I use a glue stick to encourage adhesion to bed. Once the bed cools down the print pops off the glass easily.

Gerrit, the trimming is not bad but I do sometimes struggle with adhesion. I have never tried the glue stick thing. Which one seems to work best?

I usually use high hold hairspray.

There are a lot of large pieces in this clock so I wouldn't want to do multiples of too many of them because they lifted.

The Filament itself also has quite an influence on things.
Latest batch of PETG from Prusa is very hard to get off the Build-Plate - but I often had the same problem as you before that ....

Prusa has admittedly also upgraded the Filament Settings for the Prusa-Slicer lately and (not sure) believe that they have increased the Temperature - both of the Build-Plate and the Nozzle ....

So I can honnestly not say for sure what had the most influence - but no more glue here  ;D

Latest brand is Elmer's. Prior I used Dollar store stuff but not happy with that.

Thanks Per. I have been trying raising the temps as well and I am getting some better results, but still not what I need.

Gerrit, I got some of the Elmer's when I was out yesterday. I did one of the problematic parts with it, and it looks very promising.

I mainly use Creality pla because I can get it locally and it is in theory, a decent filament. The designer of the clocks recommends plain pla because although some of the other filaments are a bit stronger, they are also, for the most part, more flexible. This clock will have at least 8lbs hanging on it so it has to resist the urge to stretch.

Fingers crossed!
