Rack System - Raspberry Pi Rack with modular trays

I have been using EvilProphet's great Rack System to hold a Lenovo m720q, and wanted to incorporate a couple of Raspberry Pis into the rack, taking the blank space. I now need to fill/tidy the rest of the rack! Print settings: Material: Sunlu PETG Nozzle: 0.4 mm Layer height: 0.2 mm Wall loops: 3 Top/Bottom shell layers: 3 Infill: +25% Infill pattern: Cross Hatch Orientation: Print with rack front facing down Support: Not needed
