The dangling power cable for the hotend and the fan is now fixed again with this model (cable holder from thingiverse - my make of it), which is much sturdier than the one before.

I am sorely dissatisfied with the (optical) print quality but for one, the Amazon Basicfil has very good first layer adhesion and the print itself is solid as it should be. And the print was to measure without any scaling (the screws to fix it to the extruder cage fit in perfectly on the first try).

3D printing can be fun again ....

Before, I tried (mostly in vain) to print the Renkforce 1.75 mm PLA 'premium' filament from Conrad but it was supremely finicky on the first layer. Once you got it to print, it does have a nice surface finish but the printing qualities are pretty sub par (in line with all the reviews of it on Conrad.de. One guy got it to print with 100° bed temperature and 230° nozzle which is extreme, considering it is PLA and not ABS ). I only bought it because I had a gift voucher for Conrad.de. 

I still have most of the 1kg roll left and I will probably pick it up again once I have a perfectly levelled print bed - as said, once it prints, it is decent. Would be a pity to throw away an almost full roll of PLA.

Currently there is a weird issue where the first 5mm print totally fine but after that the layer quality degrades - which I still need to and will fix.

The much easier first layer with the Amazon Basicfil is a nice breath of fresh air though compared to the struggles with the Renkforce.
