This is only my second entrance on a 3D design contest. I'm happy participating with « MyMiniFactory + Barclays Eagle Labs » by contribuating for this #enabledby3d program !!!
I'm particulary sensitive to handicap's situations, because I know people in my immediate and extended family who live this kind of situation. One of the main interests of the 3D printing is the customization for each object who will be manufactured. And that perfectly matches the field of disability, as it must constantly offer a unique solution to each patient, because he lives daily with its own unique situation and very personal. The world of 3D printing can make a great revolution and become a valuable aid for people with limited use of their hands (and also other handicaps, but the subject currently involves hands). It will be possible to adapt with a great precision the necessary devices for each particular case. We will help to better people who deserve better living conditions, and this contribute to a better well-being for them.
So, I've designed a modular device, who allows holding a compote or yoghurt pot, correctly. You just have to print the "Yogurt Holder.stl" first, and searching the best solution for the handle by testing one or more of the other objects designed for my project. You can go from a handful to another as many times as you want, thanks to the system of interlocking dovetail that engages from underneath the device.
*** You could merge the .stl files when you will have find the best solution with meshlab or meshmixer, and finaly have only one mechanical part by prinitng your design. You can use the "Dovetail Shape for mesh mixing.stl" file for adapting an other handle solution. Be attentive of the orientation of this mesh, there are 91 degree angles between the bottom and the two faces who will be engaged on the negative dovetail shape from "Yogourt Holder.stl". If you are not vigilant, your mechanical part won't slide correctly. It 'll be possible, but you 'll have to put your part upside own !!! ***
I wanted to design a nice object, which don't remember a medicinal device. In the specifications that I had imagined, I had decided that it had to be easy to print.
If you have suggestions or questions you can use the « MyminiFactory » website comment section. For a specifical adaptation of the handle, you can use the same way, I'll study a few case for helping you (I'd need to collect a maximum of informations (description, photos, vidéos, measuring datas).
Printing Tips :
PLA : all the object of this project have been optimized for PLA, there is 0,2mm tolerance for a good slide between mechanical parts. Optimized results with the technical spécifications below (after ABS paragraph). These choices were made based on existing and current technical specificities of FDM printing machines.
ABS : you will have to verify if the tolerance are good or not (test only the 20 first layers. If necessary, adjust a little by scaling "yogurt holder" (1.01 until 1.03).
Put vertically the object, like the .stl file on nettfab for example. (except "Long Handle for Yogurt Holder.stl" : you must have to rotate it for 180 degrees on x axis. It will be upside down).
0,4 mm nozzle.
20% or 33% Infill.
Brim, no raft needed.
No support material (except "Single 45deg rotation Left Handle for Yogurt Holder.stl" and "Single 45deg rotation Right Handle for Yogurt Holder.stl".), the objects are designed with the 45 degrees rule.
Wall thickness : 0,8mm
0,2mm for layers thickness.
