Grocery Buddy
thingiverse
Having trouble reading your grocery list while pushing around your cart? Well screw this onto your grocery cart handle, and use a phone with a magnetic backing to stick it together. I printed at 0.2 mm layer height but I think any will work for the screw mechanism. you have to glue the magnets into the holes and boy oh boy i had some trouble. Put something magnetic on the reverse side so the magnets are pulled towards the glue and not eachother (they will pop out and glue themselves together). Here's the magnets I used: Magnet Source Neodymium Ring Magnets (found at Home Depot) Visit my iTether model for a compatible case.
