Khay Thoát Nước Gợn Sóng - Parametric

This drainboard is flat on the top and bottom of the wavy section, but sloped inside so the water will drain.

There are 3 versions:

• Just the drainboard
• Drainboard with has small tabs on the bottom that will catch the edge of a sink or shower shelf.  This keeps it in where it will drain where you want it to.  
• Drainboard with tabs and a low lip around the 3 sides of the top, and one with no lip.  

I have printed this with PLA and PETG with the open zig-zag on the bed and a brim. (You could try without a brim, but it is a pretty small contact area for a tallish print.)  If you forgo the lip on the top, it should print flat (top down) with no supports (I have not tried that yet, but no reason it shouldn't print).  

Here are the parameters in the Fusion model.  I have played with the Height, Width, Depth, Wall, and NumOfWaves and it seems to be pretty robust.  These are the parameters I used for the *.stls I uploaded.  If someone need a specifically sized .stl because they don't have Fusion, leave me a comment.

If you want to try to make your own variation, I suggest you copy the version that is sitting on the origin, then make your adjustments to the version that is left sitting on the origin.  That way all of the other versions should keep working, while you are making your edits.
