This is a bird feeder for small birds. Bigger birds simply can not get in :-) .You can put food for them in the green feeder-dish in the middle. The feeder has a hole in the middle to let water out. Also the feeder can be removed for cleaning. In use, that will be necessary :-)
The peaces fit together like a puzzle and they are glued. Later I painted it with insulating primer to get rid of the “printer tool marks” you can see on the pictures.
I have no reason for the colors of PLA I have chosen other than that I had those. The 2 different colors are due the fact I used 2 printers to save time. I printed this in 0,2mm resolution with a 0,4mm nozzle. The temporary support peaces are printed with only one wall count and one top and bottom layer. Infill of these support peaces are 10%. This is to save material :-). The other peaces are printed with 3 layers for the wall , top and bottom . Infill between 20-25%. The roof peaces are printed with support generated by Cura.
The mount or ring at the top is fastened with a M3x40mm bolt and nut. At first I designed this “mount” in 3 peaces, but later changed it to 2 peaces, due to other changes I made. To make this part strong enough I used PET-G Carbon to print this peace. This material looks very nice, but it turns a brass nozzle into garbage after a few prints :-). For this a hardened steel nozzle is better, but such a nozzle is expensive ( €30,- where I live)
in the “total assembly.STL' the whole model is assembled so you can check where all the parts should go
If you have questions or do you think I have forgotten something , feel free to ask :-)
