About this 3D model

Since I changed my old two-holes faucet for a modern one-hole one, I needed to cover the extra hole, so I designed this simple cover. Print the bolt and nut with any filament of choice (PLA, ABS, PETG...) and a layer height of .1 to .15. The bolt requires printing supports. As for the washer, use any soft filament (TPU...), the softer the better, and a layer height of .2 to .3 If you with, you can use an extra sealant such as silicon to ensure it to be water tight.
