I had purchased a Pentek water filter on Amazon and it didn't come with a mounting bracket. This one has the relief button, so a cut out was made on the left side to accommodate that. Therefore the inlet is on the left. You can mirror the drawing if you need it on the right. I made this one heavy duty so it should hold up to some abuse.
I printed it in PETG, 50% infill, 2mm walls, top, & bottom, no supports or rafts.
The author marked this model as their own original creation.
