Dumbbell Phone Holder

My mom wanted a phone holder for while she worked out, so I made one for her in the shape of a Dumbbell. Make sure the Dumbbell weighs about 300 grams total for it to accommodate most modern phones, and use superglue to connect the shaft to the base for extra stability. The print profile I made includes a cube that you can use any spare filament on, weighs around 90 grams, and adds extra weight to the base for extra stability. I highly recommend doing this if you plan to slice the raw files yourself. Just add a negative modifier cube inside the base, make a simple part about 0.5mm less than the negative part (i did a cube with 65mm sides as the negative and 64.5 for the insert). Add a pause at the layer before the gap in the base caused by the negative part is closed, and insert the spare cube (make sure it has a high infill percentage for extra weight), and resume. For the counterweight, it works best if you have it just made out of the top and bottom layers for the most weight. All t
