Bike light to rack adapter plate by gpvillamil May 31, 2011

Featured Thing!

Description

I have a rack on my bike, and a light from Planet Bike. The mounting hardware for the light allows it to mount on the seat post, but then it will be covered by anything on the rack. It can be mounted on one of the support struts for the rack, but then it is quite low, and often gets knocked out of alignment.

The ideal place to mount is on the rack itself, which has a fitting for a mini license plate.

This object is an adapter for the bike light, that bolts onto the license plate fitting, and still has a functioning quick release for the light.

The OpenSCAD file is broken out into modules, so if you have a Planet Bike light set, you can re-use the mounting bracket and release lever and make your own custom light mountings!

Thanks! I think you might be onto something with OpenSCAD being two precise. I will keep an eye on this problem and see if its only SCAD when I get it. I printed this at it works great but was two big. I don't know SCAD so I remade this clip today to fit my rack. If anyone needs a smaller version of this clip or a Sketchup file try: thingiverse.com/thing:226475
I used ReplicatorG and Skeinforge 35 for those prints. No problems at all. In fact I designed the object so that the thickness of the walls was exact multiples of the layer width.

I think I posted the original OpenSCAD file, so perhaps you could try regenerating the STL from it?

I believe the problem might arise because OpenSCAD is very precise, so that two adjacent objects might share a face, and some slicers throw an error when they see that.

A quick and dirty repair technique is to just import the STL into Tinkercad and then save it again as an STL, TC does a shrinkwrap & repair on all imported STLs that works really well.
I'm curious what software you used to print this object? When I slice the STL file with slic3r (v1.0.0RC1) I get strange holes and spikes and a manifold error. I get this a lot with files I get from thingiverse. Clearly this file printed just fine for you, I can see the picture. I was able to "repair" the file with netfab and its printing now but I assume you did not have to repair it before printing. So what might I be doing wrong?

Instructions

Print it. Use two 7/32 or M5 nuts and bolts to attach it. Might make sense to use a lock washer to secure against vibration.

Hi Sean!

I sent you a reply a week ago to your email, I'm delighted to have the part featured. I'll PM you some additional info
This is so great!

All bicycles racks I own, have that space/holes!! And all the lamps are equal (because they come from China).

I use bicycles a LOT and I also use the lights in the night :-)
Cool, I was thinking of making something like this a couple of days ago!
