Freestyle Libre Sensor Wrenches

My mother has arthritis and cannot open the sensor's packaging. She lives alone and needed to get them open. I made these wrenches to be a fail, crush-proof way for her to get these open.

I am only supplying it here so others can benefit, if needed.

I added modified versions for hanging and have option magnets (5mm x 3mm round disc).

If you want the magnet option, they are imbedded and will need to pause the print (around layer 17 if using .2mm layers) to insert and possible glue them in place, then continue the print.

UPDATE 3/3/26: Added wrenches scaled down for the new sensors as they are smaller now.
