I had similar layer adhesion issues with ABS. I've switched to PLA and had much better results on an Ultimaker.

Ha! Turns out i need your fuse box cover. Going to print it tonight after i fix an issue with the printer (fan duct is sagging). I've moved onto PET from PLA and i'm extremely happy. Much more durable.

Anyhow - thanks for sharing the fuse box cover design. :)

Alright just finished printing the cover in PET and it works fantastic. Fits nice and tight - awesome. Since we're replacing the fuse cover i figured we needed a replacement label. I went ahead and reproduced the original label in the PDF found here:

I found that the label will print on a 2" x 4" sticker then can be trimmed down to exact size.

That is very cool!

I did eventually make the switch to PLA too but haven't printed much for my car. With my busy work schedule, all I can do is work on my quadcopter. PLA prints sooo nice (and smells wonderful!)

I also switched to an E3D Extruder. It's all aluminum and virtually no clogs (knock on wood)
