Pencil/tool stand in shape of insulation hatch. All architecture and engineering students will love that.

The model is designed in Fusion360.

The print is very easy and there is no need for supports or brim. Just make sure that it stand on the platform nicely.

The model in foto is printed on Prusa MK4 with 0,4mm nozzle and 0,2mm layer height. Filament used is Prusament PLA Army green.

I hope to see many prints in comments! Also appreciate any feedback for improvement.
