I cured this piece before the Model Cure was released. I oven cured with slow ramp to about 325 F and left it for 1 hr. Larger items like this can crack if ramped temp is too fast.
Sun curing and Model Cure method are prob best to avoid over "cooking" in the oven and avoid cracking.
You could Sun cure also maybe 5 to 6 hrs. of full Sun. Bowl of water and maybe foil underneath for reflected UV.
In the model cure would lay on it's side with supports removed and cure 6 min and flip over and cure another 6 min. Really can't overcure with the Model Cure. Add more time if u want.
Dance like nobody's watching!
