Hi I made this for my elderly Parents to aid them in opening jars lids which were hard to open. But anyone can use it. It works well to get them stubborn lids off. Print in place model. No supports needed. I have included 2 print profiles for this model. 1st is a high strength one. (jar opener) 0.2 layer height 6 walls 25 percent infill 69.85 grams of filament 2hr 19 mins print time 2nd is a normal strength one (jar opener normal) 0.2 layer height 2 walls 15 percent infill 38.5 grams of filament 1hr 23 mins print time I would suggest using the high strength one for the added strength.
