The perfboard almost guarantees that your prints will stick to the build platform. The consequence is that you need tools to remove the object and clean it up. The gloves and scraper, thankfully, are included with the printer.
Because it has a large, flat surface already, this print probably doesn't need a raft, the layer of extra material at the base of the Knife Assistant. I printed one anyway for the purpose of this demonstration.
The included X-Acto knife handles the fine removal well enough, but you need to be careful not to remove material from the object itself. Gloves are also recommended here.
Total cleanup time for this object was about 5 minutes. Larger objects take longer, obviously. Thin or otherwise fragile objects can also present a challenge.
