So I love the original design by Balze and they've doe the world a favour for giving us an excellent solution to a badly designed taillight.
But the problem I had is that printing on my 3d printer doesn't yield good layer adhesion. So when yuo screw into the holes my print was splitting.
So this remix splits the screw posts into two parts: One half stays attached to the backing plate, and the other half leaves you with two rings that slip neatly over the posts. The idea is that you can print at 90 degrees to each other, then when you assemble the part there are no weaknesses in the screw posts. (Same principle in laminating wood at 90 degrees between the layers).
- print in the current orientation (backing plate vertical, two cylinders flat)
- use brims (the backing plate is too thin to adhere properly to the plate)
- use scaffolding
- after printing slip the two rings over the posts and press them down as far as possible. It should be snug enough but glue if necessary.
I didn't take pics of the final poduct but it worked a treat and mounted to the bike without splitting.
