This model requires finishing. I am a complete noob with blender and the backside is not perfectly flat. i reccomend to do a quick cleanup with a plane in blender if youre blender skills is more adueqate than mine. In every case i strongly suggest ataching the plaque to a wood base using epoxi glue.
For printing. take care to reduce stringing and eliminate any stringing with a quick touch of a flame. I printed it on .2 layer height. Slight supporting is required.
The model has an extremely high resolution. I know for a fact that PrusaSlicer can handle it, however i have confirmation from Printables creator @WilliamSC65 that UltiMaker Cura will crash upon importing the model.
As usual i declare the design public domain, any attribution is greatly apreciated but not needed (because demanding it would be hypocritical on my end).
The author marked this model as their own original creation.
