Add a touch of personality to your Microserver with a customised nameplate. Add any text or graphic you like using Prusaslicer.

In the past I've used sticky labels but they lose their stickiness after a year or two. This nameplate is physically inserted into the USB port. It also serves as a dust cover. 

WARNING: This model shouldn't damage the USB port but proceed at your own risk. 

The nameplate is intentionally blank. You can add a multi-material text layer in Prusaslicer. If you have a toolchanger or MMU this is super easy, but this works on single-extruder printers too. The steps for a toolchanger or MMU.

1. Import the STL into Prusaslicer and spin it around until you're looking at it from the bottom, through the heatbed.
2. Select the nameplate and choose the Text tool (T). Change the font and position as you like. Choose the MODIFIER operation.
3. In the Object List right-click the Text object and choose the second extruder. Slice and print your customized nameplate.

For single-extruder printer without an MMU.

1. Change into Expert mode. Select your printer system preset and go to the Printers configuration tab.
2. Under General - Capabilities increase the Extruders number to 2 and tick the Single Extruder Multi Material checkbox. 
3. Under Custom G-Code - Tool Change G-Code textbox add the command “M600” (without the quotes).
4. Under Single Extruder MM Setup change the Cooling Tube Length to 0, the Cooling Tube Position to 0, and the Filament Parking Position to 0.
5. Click Save Preset and use the new User Preset for slicing. The screenshot shows all the changes required.

Then follow the earlier steps as for a toolchanger or MMU. You will have to manually change the filament when prompted and remove the purges with tweezers.
