Add the 3D printer from "First Contact"
For fun, offer parts of the 3D printer to unlock. When complete, we can place it and even add a few of our unlocked items (anything visitors can manipulate) to its "memory" that get randomly selected for printing. Include the other "disks" as well (gun, butterflies, noise makers).
Add the "monitor" with "keyboard" that allow users to scroll through selections for more predictable fun.

I have serious question regarding the 3d printer, I am currently facing some issue with the 3d printer where it is showing an unknown error code called lexmark 900 firmware error, I have never faced an error from the printer, however, I had help from https://printerssupport.co/fix-lexmark-900-firmware-error/, but proper solution is needed to help me solve the issue, I would really appreciate the help that can be provided from this blog.
