About this 3D model
This is part of an Adaptive Aid assignment for EE4777 Open Source 3D Printing at MTU. The cost of this 80g object using Hatchbox PLA is about $1.20 in material. A comparable commercial offering can be found here: https://www.arthritissupplies.com/handybar-helps-getting-in-and-out-of-a-car.html for $25.95. A solid press fit can be made if the stub.stl file is scaled to 98%. For strength, stub.stl should also be printed on its side.
