Dog Gate Replacement Rods

Included two pictures - one closed, and a close up photo showing the nut. The TPU insert is barely visible in the second one...I added an extra couple of millimeters of thickness since then.

I used 5/16 bolts & nuts, as a substitute for 8mm bolts that I think were the original (now lost) bolts. The design can probably handle 8mm bolts/nuts, but no promises...the hardware store I had access to, the 8mm threaded bolts were only 60mm long. My project used 5/16-inch x 4-inch hex tap bolts (Lowe's, product number 214123 - a two-pack of bolts).

It does notneed glue, but it does make it easier to assemble and put up. (Once the gate is up, glue is unnecessary.) Glue nut to inside of spinner, glue insert into base, glue top of bolt into other side of base. Okay without.

If you don't use TPU to make rubbery-end stop, you can cut down a rubber stop found in the furniture feet area, which is what my first prototype used.

How I Designed This

Additional Design Considerations

I did consider building plastic threading (a nut) into the spinner. Blender has a nice plugin called "BoltFactory", which is really good. The 4 metal nuts added 64 cents to the final cost and are more durable...and I was going to the store already for the bolts. If I already had the bolts, maybe...
