Posh Bird Box Hotel. No supports are required as long as the roof section has 1 of the outer tops, flat to the print bed. Easy to print and only 2 parts. Only down side is it takes quite a long time to print. I had under extrusion issues with the Grey PLA I used for the Box bottom section. But that was because I was using up some old, cheap PLA that has given me issues before on a completely different printer. The Hotel name can be changed to your own TAG or name if required. The hole is 28mm in diameter, which is ideal for most small birds such as blue tits and robins. The roof simply slots on and off for easy removal of last years nests.
