Kitchen Drawer Backplate

This is a backplate made to fit our 50ish year old Levitt kitchen drawers. The big box stores stock them at about $1 each but those are very thin and break easily. These are a bit beefier. I didn't put screw holes in as I intend to attach them with a pneumatic stapler.

This is my first part from design through printing so some workflow notes: drawn and extruded in Progecad (AutoCAD (which I know) clone), then exported to Fusion 360 (which confuses me) to remove and join some bits and saved as an .STL file. Sliced using Slic3r through Repetier Host and then uploaded to the OctoPi (Raspberry Pi 2+) and printed.
