Here's some signage for your 3D Printing area with different possibilities. There are 5 build plates depending on what combination you want. Plates feature:
Plate 1 - Letters: 3D PR
Plate 2 - Letters: INT
Plate 3 - Teeth wheel
Plate 4 - Letters: ING
Plate 5 - Word: CORNER
The teeth wheel has holes at the back so you can slide it on a screw or nail. The letters I have mounted with double-sided 3M tape, as for the word corner.
Dimensions:
Only for Letter T: 97cm x 78cm x 20cm deep.
For the word 3D Print: 67cm x 78cm
Extra files:
I have included all the step files for those that want to make changes or print with another printer.
