Extra Battery Mount Radpower Radrunner 2

I remixed this so that I could mount an extra battery to the water bottle mounting points on the down tube. You can use the existing screws from the bike or a pair of M4 button head screws you may have on hand.

There's a pair of 3/16" thick mild steel bars on the back for strength and rigidity. They are held in place with 10 M3 flat head bolts with nuts and lock washers. A small dab of blue locktite on the threads might be a good idea too.

This was printed with ABS and a layer height of 1.5mm. The holes for the bolts are countersunk but they might need drilled out with a countersink bit for proper fitting.
