This is the dashboard switch cover. The model is designed based on the original cover from my 2002 Toyota Tacoma. It should also fit Hilux/4Runners/T100 as well. I've pictured the printed version next to my original one.
To withstand the summer temperatures and winter cold, I would suggest printing this out of ASA, ABS, or PETG. Printing in the orientation seen in the 1st picture will lend itself to a stronger part less likely to snap.
The author marked this model as their own original creation.
