The rollover is not only for an aesthetic reason.
In fact, to print well complex parts it is essential to have a constant thermal environment.
Small parts print without enclosure, but a very high or complex part requires a constant thermal environment (just have a look on professional machines, they are all with enclosure and heated chamber)
For example, in our tests, on some parts, just open the door of Spiderbot caused marks on the printed part.
Spiderbot is ready to evolve into a professional printer. We are working on a ventilation system and heater of the enclosure, it will be offered as an option for new customers or upgrade for existing customers.
