Yes and yes
Wich nylon are you using? Some need more temp than others to bond good between layers. My latest nylon prints was around 270, lower and I had pieces falling off.
- Cover the printer completely - you want the air temp to get much higher. Around 35C is good enough and still safe for the steppers.
- Make sure fan is at the lowest value where it still spins (1 to 3% for a UM3, around 30% for a UM2 and so on).
- Nylon absorbs water from the air crazy easily. You might have to bake yours at 100C for a while but it looks okay - if it's totally too wet it will his and sputter and sizzle as it prints. But there is a point in between where it's quiet but it comes out foamy instead of normal. It looks fine in the picture though (hard to tell).
- Bed at 80C minimum - more to heat the air then the nylon. 100C bed is fine for nylon also.
- Layer heights at least 0.1mm. 0.15 better - that way there is more thermal mass to melt the layer below.
Even if the cracks go away you might not have improved adhesion enough. Purposely break a part and if it breaks along layer lines you still don't have good adhesion - it should break along random lines - not layer lines - if you do nylon right. Actually a part this small - you probably won't be able to break it without some special tools so if it doesn't break despite your best abuse it's probably fine.

Hi,
did you select the Nylon profile in Cura? Did you use Cura at all? If not, which other print settings did you set?
