Our team has 3d printed VEXpro Gussets for our Versaframe. These have proven to be incredibly useful for prototyping and have held together our robot very well. With shortages of materials and unreliable shipping time, the gussets we printed have made a great substitution for the VEXpro ones. Only problem is that the holes are always a little bit too small but drilling them out is no problem.

You can see some of the gussets we have are non 3d printed for extra support but the colored ones we printed on our Makerbot.
