1 inch steel box tube end cap

thingiverse

This is a custom end cap engineered to snugly fit within 1-inch steel box tubing. To ensure a secure hold, I strongly advise sealing the cap with RTV silicone sealant, thereby significantly enhancing water resistance. The inner weld seam of the tube will provide initial retention, but for optimal results, this extra precaution should be taken. This end cap was specifically created to fit perfectly onto my dad's ATV's uhoh handle. Designed using Fusion 360 CAD software.
