Adapter Spacer/Endcap For 5/8ths(22mm) diameter rods

I have included the obj files if anybody wants to adjust it for there own needs. as this is my first remix it was made in tinkercad (still need to learn fusion 360) it is simple but functional. I printed it with the same settings I used for the bracket and it fits pretty good without too much force needed. Also if you use dowel rods like I did you might need to sand them down or it might be a little loose. The dowel rods I had were not super uniform in the diameter it was snug on one and a little too tight on the the other. I also added a hole on the endcaps to use a screw to lock it in place. If need be could also be glued. I also created a center spacer/adapter with a little looser ID so it can be used with more than just end brackets while I have not tested this out because for my space I only needed the ends. Supports are recommended as the hole for a screw gets a little messy otherwise. if you want a nicer looking end, support it from the under side (should already be oriented that way) it will use a little more filament but as you will see in the pictures the test piece I printed looks a little rough. Hopefully someone will find this useful.
