Ridgemonkey 750 3omm extender with cover

i designed this ridgemonkey 750 hopper extender and cover for a friend and he liked it so decided to share it. the extender is an extra 30mm high with a cover to prevent the ducks from having a snack. the cover is held to the extender with 5x2mm magnets, the holes are made to be a very snug fit but will go with some pressure, i use the flat part of the knob top help push the magnets in place then just fit the knob with a screw. for two color printing i just put a pause into the print via the slicer software to change out filament.

*added extender with 4mm walls for extra rigidity
