Vent Cap Wrench for Basement Watchdog sump battery
Description
My Basement Watchdog Sump Pump Backup Battery Has Vent Caps That Can Be Somewhat Tight And Hard To Turn. I Top Off The Cells With Distilled Water Every 6 Weeks. This Wrench Makes The Job Much Easier. The Example Shown Is Hatchbox Red Pla, Printed With 15% Infill, 5 Perimeters Minimum, 5 Bottom Solid Layers. At 35Mm/S It Is A 3-Hour Print With The 15% Infill. Darn It ! The First Time I Used The Wrench To Top Off The Battery, I Discovered That The Yellow Cap That Holds The Level Sensor Rod Has Six Ribs Instead Of Eight ! Why They Make Them Different I Have No Idea. I Don'T Really Want To Print Another Wrench Just For That Yellow Cap. That Cap Turns Fairly Easy On My Battery Anyway, So I Will Just Keep Doing That One By Hand. Update 12/4/2017: I Uploaded A Version Of The Wrench That Should Work With The Six-Rib Cap As Well As The Eight. I Have Not Tested It, And I Don'T Know How Strong It Will Be With Only Two Blades, But It Is There If You Want To Try It.
