Wooden Shelf

prusaprinters

I designed this small woodgrain shelf to display my crawfish and my butterfly. Although the entire shelf prints in just one piece, it simulates the look of a shelf made of 16 individual pieces of wood arranged in a decorative pattern, supported by an integrated bracket made of another 3 pieces. If the pieces are finished in an alternating pattern, then you get a nice pinwheel or checkerboard pattern. But in retrospect, designing some of the pieces as separately printed inlays would've made that easier to do.Print SettingsSupports:  NoResolution: 0.15 mmInfill: 5%Filament: Wood PLA brownPerimeters: 1Horizontal shells: 2 top, 2 bottomTop & bottom infill pattern: Octagram Spiral (It complements the pinwheel arrangement of the woodgrain patterns)Internal infill pattern: Gyroid (Its waves look natural enough when a bit of light shines through this slightly translucent shelf.)I used a G-code postprocessor to vary the temperature along the Z axis for additional woodgrain effect. The settings that I used were as follows: temperature range 205 to 233°C, 2-mm grain size. But this postprocessor has two undesirable side effects that I had to work around:It overrides even the first-layer temperature that I specify in PrusaSlicer. With my wood PLA I found that I get the best first-layer adhesion at 215°, so I manually adjusted the temperature on the printer as it prepared to print the first layer. Manually editing the G-code would work also, if you can locate with confidence the part in need of alteration.It prevents the printer from cooling down after the print completed. The first time I tried it, it left the printer hot all night. Knowing this, I manually turned off the heat when this shelf completed printing. Again, manually editing the G-code would work also. If I find myself using this postprocessor much in the future, then I'll look into that.
