Small Bird House

This is a birdhouse for small birds that can be disassembled into three parts with threads.
The body is made of PLA and the roof is made of PETG.

I used "ISO Pipe Threads" for the threads.

The diameter of the entrance is set to 28 mm, which is a suitable size for a titmouse.
The size can be changed by using attached STEP file.

"Fuzzy Skin" option is used for printing.

I have uploaded CURA 3mf file for your reference.

The skin is set to be coarser than the standard Fuzzy Skin setting of CURA.
I used support blockers (*) to prevent Fuzzy Skin from covering thread. Roof does not need support blockers, but Fuzzy Skin should be set the same as other parts.

* How to add Fuzzy Skins for body parts.

Add "Support Blocker" and Select Mesh Type for "Modify settings for overlaps".
Size: X,Y,Z=200,200,100
Position: X,Y,Z=0,0,0

Select "Cutting mesh" and add settings for "Fuzzy skin".

Fuzzy Skin: Y
Fuzzy Skin Outside Only: Y
Fussy Skin Thickness: 0.5mm
Fussy Skin Density: 1.25 1/mm
Fussy Skin Point Distance: 2.0mm

After the printing, water-based waterproofing paint was applied, but it may not be necessary.
