This mount has a rail system inspired by the Pikatinny rail system on guns (except the profile is rotated for easy printing). You can attach other other devices, no screws required, around this mount by printing other rail adapters or design your own.
You probably also want to print the Raspberry Pi Pixa Mount. Use the Pixa Standoff model to connect the two board mounts together. You should screw the Octopus mount to your printer but the RPi mount doesn't have to be screwed to the printer if you use the PixaStandoff model to secure it.
The author marked this model as their own original creation.
