<p>I am currently trying to print a company logo on another part I have printed in a different colour. To try and maximise the strength of the part, I need to print the part on a different orientation to what I intend on printing the logo on. As a result I need to in a sense re-adhere the part to the bed so I can print the logo. I am using PLA filament on a spring steel sheet (the default sheet with a Prusa Mini).</p>
<p>Any ideas would be appreciated before I accept defeat and just glue the parts together.</p>

Adherence is the 3D printer's worst enemy.
I use painter's tape, but I heard that you can if you need to remove and re-stick it back, heat the part lightly with a lighter and re-stick it back to the bed. Never tried but I'm guessing you would need to cool the bed, heat the part, and stick it back then reheat the bed and continue to print.
Glue sticks can maybe help or even hot glue. But I would be afraid in that case that the part wouldn't be level hence the glue would be to tick.
