Dumbell U Clip for Barbell

These are U clips designed to be able to put dumbells onto a barbell for extra weight for those who need more weight and don't have plates, especially useful for adjustable dumbbells.   I only printed for myself at 100% infill just to be sure and have had no issues for more than a year now.  They have support 90lbs hanging overnight.  The design is based off of  https://uclips.ca/products/uclips without having to spend that amount of money.  I have included original dimensions that match the link, I placed foam tape to make it a bit more secure for my bowflex dumbells.  I have also included a file that is 75% wide and can support the diameter for the bowflex select tech dumbbells. 

I had some trouble with adhesion using brims and raft, the moving head would knock off the model at like 75% height. It could be that my plate was not clean enough so I have included a webbed version to add an extra layer for adhesion, this layer is very thin and can be traced out after print with a scalpel after.
