backside purge solution with a drawer

MotivationUsing a p1p inside of a closed rack to: silent the printer reduce the vibrationseliminate temperature fluctuationsprotect the printer against draftcontrol the temperaturekeep it dryfilter fumeprotect against firesecure the power networkQuickly run into the issue that the bambulab printer purge at the backside. A lot of purge! even without using the AMS.No proper way to handle the backside or use one of the 300 purge collectors that needs to have access to the printers back side.So this one with a big drawer was made. Let's get startedPrint with PLA or PETG, this is a very easy print you need no supports.I use a strong 20x40x5 mm magnet to fix the purge box to the printer but this is optional.There is no angle lower than 45° so you need no support for the ramp and no support for the magnet cave. It's a functional part so i printed in draft on the hot sheet with 0.4mm nozzle without glue.You may check the bed flatness with this test model upfront:flat bed / https://www.printabl
