3D printed housing?

Since the development of a standalone Super8 scanner is faster than expected thanks to the help and software of Manuel Angel, it was high time to look for a suitable housing.
Since nothing is final in terms of setup, I was looking for a flexible solution. I’m not a technician, but the system profiles seemed like a nice solution. Since I recently ‘built’ a Prusa i3 MK3S it seemed natural to me to print these profiles. The photo shows a part of 30x60x17mm.
Is it sturdy? It was no problem at all to carry my weight of 84 kilos!
Does it take a long time to print? About an hour and a half for every centimeter.
