it took me some time to get the error out of this file but here it’s.
I made this as a 100mm wide patch. that is best printed with a 0.2mm nozzle.
but if you like to print it bigger then use the scale option in cura and leave the Z at 100% scale
so far I have tested over time does PLA + and PETG work well with the velcro with a the added “glue” on it. so it can be worn as a patch. but you can do something else with it as well.
I have not tried flexible materials with this technique jet. but but out of the two PETG will give you a bit more flex.
