Boot Jack to make removing your boots easier. (If you know, you know).

Note: This has been sized for an A1 printing plate. It is too big to print on an A1 Mini.

You may want to increase the infill for a stronger print, but it does print and function fine with minimal infill and PLA. (Really depends on how tight your boots are).\

NOTE: Added a new version (Boot Jack v3) with a bevel at the rear to better help distribute weight. Also, have set 20% rectilinear infill, and 5 wall loops as per recommendations from @altcandidate (thanks!)
