Single Joy-Con Grip by 3DBotMaker on Thingiverse

This Thingiverse object is a grip for a Nintendo Switch controller. These controllers are very small and somewhat uncomfortable to use on their own. The grip is designed to increase the size of the controller by giving your hands something bigger to hold onto. It is designed to make it easy to insert and remove the controller, while (hopefully) still holding it tightly in place. There are also holes in the back so that you can push the controller out when you’re done using it.

After some planning, I realized that I wanted to make some changes to the model. While I knew the grip would be helpful on its own, I wanted to take it a step further and make the handles longer, making it shaped more like a traditional controller. Another improvement I was originally planning to make was changing the back side so it would be easier to hold. On the original model, the grip is perfectly rectangular, so I considered making the back curved to give my fingers an easy place to grip.

F|F Iterations

Original Model

Single Joy-Con Grip by 3DBotMaker on Thingiverse

This is the printed base model from Thingiverse, with no modifications added.

Modifications

After seeing how the model looked in the physical world, I started to make some changes in Tinkercad. At first, I planned on extending the handles and making the back side curved. However, after testing the original print, I thought the straight back still felt pretty comfortable, so I just focused on making longer handles. For my first iteration, I simply added some rounded shapes in order to achieve this.

After working on it some more, I wanted to make sure that when printed, the handles would fit to my fingers more naturally, so I decided to replace these handles with custom extrusion shapes. It was a bit hard to integrate my additions smoothly because the original model includes rounded edges, but I tried my best to align it as well as possible.

The base model came with instructions to print with 10% infill and .25mm layer hight, so I used these settings to print both the original model and my remix. The second version ended up, structurally, as I expected, however the “layers” didn’t seem to be as smooth as the original print. The settings were exactly the same, so it may have been because I used a different printer model for the second version. After testing my remix, I found that the extended handles did make the controller more comfortable to hold as I intended, although they could have been even longer to fit my entire hand.

Final Iteration

I then went back into Tinkercad and tried to figure out a way to make the handles match the original model better. The process was very tedious, but ended up accomplishing this by adding hole shapes around the handles, which “carved” the straight edges to be rounded.

The final model and print ended up working out very well. As I was smoothing out the edges in Tinkercad, I was worried that it would come out blocky, but once I printed it it actually ended up being pretty smooth. Because I didn’t make any changes to the base model, the controller fits perfectly inside the grip. It is snug enough to stay in place while still being easy to insert and remove. The handles are now a good size, and the controller fits comfortably in my hands. Overall, this project was very challenging, but I am very happy with the way the final product turned out.
