This design serves as an object to lay your chopsticks on so they don’t roll on the table. The fish prints first separately and is then inserted int...o the chopstick rest while printing. Choosing the correct slicer settings is important to make the model hollow.
Notes:
The colored spots on the... fish are printed using a layer filament color change.
The transparent part of the chopstick rest must be printed with 0% infill.
1 perimeter at 0.2mm layer height is optimal for viewing purposes.
To insert the fish it’s best to set the printer to make a stop while creating the g-code instead of waiting by the printer. I would say setting a color change is better than a simple pause even though you don’t want to change the color of the filament. This is because as the printer is waiting for you to insert the fish, filament will ooze out of the nozzle and a pause will not extrude additional filament when returning to the model. Since the model is printed with a single perimeter this can result in a gap in the layers which would ruin the whole print. Whereas with a color change you can be sure there will be fresh filament in the nozzle when you resume printing.
