I'm still on my first few prints and the kit the printer was assembled from was the worst piece of junk I have every seen so still working out the bugs, hence the print is not as aesthetically pleasing as I would like. However I use the 'hairspray' method of keeping ABS on the bed and over time this has built up to the point where the bed is uneven so I have printed this and use it to scrap the bed down between prints. This was ideal for that thanks very much for the design and sharing of said design.
I used supports in the holes as my printer is not yet very good at bridging even the small area above the holes. However the support was easy to remove and didnt effect the final piece.
