Xiaomi Power Bank Bicycle Seatpost Mount

thingiverse

This power bank holder attaches securely to your bicycle, ensuring you always have a reliable source of power. The holder is specifically designed for an older 10400 mAh Xiaomi power bank, as shown in the final image. The holder can be attached directly to your bike using zip-ties or by printing the stem_mount parts, which allow you to mount the holder anywhere on your frame (27 mm diameter). This design consists of four key parts: * Holder.stl * Cover V2.stl * Stem_mount.stl * Stem_mount2.stl (print this one twice) If you want to attach the holder using zip-ties, simply print the first two files. Otherwise, print stem_mount.stl and stem_mount2.stl (twice) to securely mount the holder to your bicycle frame. The cover can be attached to the holder in two ways: * Tap the holes in the holder * Insert heat set threaded inserts into the holder I chose to attach the cover using heat set threaded inserts. You can find a link to purchase these below. To insert the heat set threaded inserts, use the tip of a soldering iron to gently push them into the holes. Avoid heating the threaded inserts for too long, as this can cause the surrounding plastic to weaken. This is all the hardware you'll need for this project: * M4 x 20 bolts (4): <https://bit.ly/2H4cpQf> * M4 nuts (4): <https://bit.ly/2LlCGOd> * M3 x 6 bolts (4): <https://bit.ly/2vEBScs> * M3 heat set threaded inserts (4): <https://bit.ly/2JnzFuh>
