Diabolic heater pipe cover (15mm pipe)

My brother beautfully renovated his bathroom with attention to detail.

Stock heater pipe covers just did not match, so I created this one, with a 15.5mm hole. Easy job, using the snap connectors feature of Prusa Slicer. Kudos to the developers.

.stl export did not include the snap holes, so I uploaded the .3mf file. 
Considering the heating supply temperature, I chose PETG. 

Brother is happy and so am I.
