modular plate and M20 attachement for Apollo Bird Feeder

the Apollo Bird feeder (https://www.vogelwarte.ch/de/shop/nisthilfen-und-futterhaeuser/futtersaeule-apollo) lacks a plate to catch the food. here is a modular plate (40 x 40 cm) that screws in the bottom ~M20 thread of the feeder and same thread clamp attachment for the balcony reeling (needing 4x M4 screws and nuts). 

adjust the clamp attachement to your needs. you most probably do not have the same balcony as i do, so i do not provide gcode here, only stl files to be modified.

print everything in outdoor stable materials. i used PETG and colorfabbs XT materials with good experiences.

the center piece with the M20 thread i suggest to print in at least 5 perimeters, as the layers on the thread hold the whole thing stable.
