I created two versions of the original model; one uses less filament since part of the original isn't necessary, and the other increases the durability of the centerpiece by doubling the thickness by 1mm. It felt a bit too flimsy to me.
I printed the version that uses less filament with PETG 0.4mm with soluble support material for the holes. It was probably overkill, but I had a lot of failed prints from placing it on the bed in different orientations
V2:
Not much different about the stl of the horizontal from the “more durable model” but I remade the Fusion file from scratch so that it would be easier for people to edit. I also added a version with vertical pegs although it needs quite a bit of support material
The author remixed this model.
I removed the area above the screw holes since it's necessary for function. I also have a version with doubled depth for extra durability.
