Simple cable tie mounts that you would apply double stick adhesive tape to.
Dimensions are:
19mm x 19mm
Fits up to 4mm cable ties.
You could scale this up.
Im am yet to print these but they are modelled off a physical mount i have at home.
I plan to make versions for large cable ties.
Update
I have also included a version with a screw hole that fits upto a 3.5mm screw as requested from another user.
