Raise3d N2 Riser

My Raise3d N2 has been very good to me, but it needs a little rise in the lid design to clear the bend in the filament tubes as they enter the extruder. I use mostly PLA, but where the N2 sits is near an AC duct and the N2 needs the lid.
I made these risers to sit on all 4 corners and bring the Plexiglas lid up about 30mm. You may want to go a little bit higher as the filament tubes still hit the lid when it goes full right.
I put holes in the riser so you could add set screws to lock them to the main enclosure, but the riser fits tightly on the main enclosure, such that I didn't use any. The holes are sized to allow self threading standard 4-40 machine screw into them.
