Just wondering what the most odd ball thing you have printed so far? Mine is this ultra thin mouse mat I printed yesterday, have to say the standard PEI SM plate gives a lovely glide surface!
What an excellent idea! And it will take a graphic design.
What layer thickness and how many layers were applied.
0.16 layer x 2
then a little bit of double sided tape in each corner to stop it moving
Thanks! 
Printed in PLA? TPU? PETG? That’s actually pretty cool idea!
Mine was printed in standard Bambulab PLA
