It comes in 2 identical parts so just print the model twice.
Instead of the bolts, I've used velcro straps just to hold it together, however I'm looking into welding them together.
Settings used (Printer: Ender 3):
Print time for 2x pieces = ~6 hours
The author remixed this model.
Just edited the original model to remove the bolt securer. Part of the top of the model has this weird extra bit from one of the bolts, but I'm too lazy to fix it and this is my first time doing this.
