I created this repatcher since I got allergic reactions from the glue on my Omnipod-patches. I use the template to cut a different patch using a pair of scissors (https://www.ikea.com/se/sv/p/svaerdfisk-sax-set-om-2-rostfritt-stal-gra-graturkos-60563431/) around the patch and and using a scalpel to cut the hole for the needle.

Then I remove the old patch from the Omnipod, put the Omnipod and the new patch in the Repatcher, add some hot glue to the pod (https://www.clasohlson.com/se/Limpenna-Cocraft-HGM-3.6-LI,-batteridriven-3,6-V/p/41-2551) and fold down the Repatcher to get the patch in the right location. Then I turn it around and add some glue in the joint at the front and back to make sure It sticks and to avoid dirt getting access to the needle.

I printed my Repatcher in PETG but I guess PLA would be fine too.
