Bee Hotel

This bee-hotel can be combined by using screws (3mm tread, max 7mm screw head) or glue together with wood-glue using PVA as main ingredient.
The Hive has four sizes of cells 4mm, 5mm, 6mm and 7mm. The cells are from outside to inside 45mm, 50mm, 55mm and 60mm deep. The reason is that there are different sizes of bees and with their own preferences in size and depth of the cell.
I suggest using the most nature based filament because bees don't like other materials. I'm going to use wood PLA because it gives a nice wood-like texture and PLA is biodegradable.
When I've printed it I'll make a picture and share it here of course.

Added parts: borders to make it look nicer.
Added parts 2: butterfly slits and ladybug holes (put some nice wood excelsior inside)
