Yeah, you could've used acrylic solvent to weld the parts back together. It melts the outermost surface of each piece so it can create a rock solid joint. JB also sells a PlasticWeld, which works great, much better than the standard formulation. Considering it's already broken, you may want to go with something like that instead, so you can actually add more material back to the break site to give it more strength to prevent breaking in the future - something the solven't cannot give you.
