About this 3D model

This is a seat belt grabber assistant that was designed for the ease of grabbing the seat belt for persons with trouble performing this task for any reason. I have seen other aids online that range from $8 to $25 but are half the length of this one. This whole design takes about 232 grams of PLA at 50% fill density. With a $20 1kg roll and the included hardware this design costs about $6, which is a significant differenece from $25 and it is twice the length and has room for improvement. Original seat belt grabber off of Amazon https://www.amazon.com/Seat-Belt-Extender-Pros-1008/dp/B004I9KGJY?keywords=seat+belt+grabber&qid=1540475070&sr=8-2-spons&ref=sr_1_2_sspa&psc=1&smid=AFDMEKAPSL95D. It is fairly close in price but is smaller, looks flimsy, and is have the length.
