I printed two collars that I thought would fit the dowels perfectly, but they were too snug. I sanded the inside, and they both worked beautifully. I can quickly find the center with a steel rule, and the snug collars probably do not need zip ties to keep them in place.
My fiance's phone case is 20mm deep, so I designed a pair of feet to extend one of her phone stands. I created the parts using the minkowski() function in OpenSCAD to round the edges, and it turned out great. I printed it on a resin printer with no supports, and it fits her phone perfectly.
I enjoyed using small screens in my projects, but mounting them can be challenging, especially since they are square with small holes. If I made one generic solution, others could easily add screens to their projects. I chose a 0.96" OLED screen for its affordability and ability to display several lines of text. My design included a mount that sandwiched the OLED between a top cover that would conceal the electronics and a bottom that allowed for circular hole mounting.
I modeled my design in OpenSCAD. For now, I had to estimate some dimensions, like screen position and hole diameter. The top ended up simpler than expected; I added a few risers for stability instead of complex internal shapes for the screen and components.
The first print turned out well, but the threaded stalk and nut need better tolerance. The top and bottom fit well, but I plan to add a "slop" variable for easier fitting on less precise printers.
I increased the thread tolerance to reduce sticking, reduced the mount's diameter by 0.5 mm, and made that variable visible. I countersunk the bolt holes and included an anti-rotation peg that can be adjusted to zero if unnecessary. Lastly, I enlarged the threaded stalk for the OLED screen header pins.
The rest of the summary posts have been arranged by date.
