Flexible straps - cable straps

Flexible cable straps, 2 types, each 200mm. Print with TPU, rectangle infill at 20%. When I print, I up the infill near the posts where it connects to to 50% for added reinforcement. I included the slicer 3mf file for reference. I'm not sure why the file size for the round one is so large. I used OnShape to make it and used the Loft feature which may be causing it. If you use OnShape, they are available in the public domain files with OnShape. I set them up with variables so you can create different sizes (length, openings, hole spacing, etc.) by simply changing the variables.
