Good afternoon!

I have a Da Vinci Jr. Pro, and I have trouble printing some smaller parts. For instance, this raspberry pi case https://www.thingiverse.com/thing:2294759/ There are 4 little pieces that go into the screw holes to hold it in. These all end up slightly misshapen, and won't fit through the holes.

I usually print at 200C, 30mms, with Hatchbox filament. Is there any tips to try? More/less heat, slower/faster? I've tried a few different settings but nothing seemed to get it totally right.

Thanks!
