Prevents your u-lock from being stolen while you are riding
Update: Check out the customizable version
A mount for u-locks on bikes. Provides a lot of settings to fit on your bike and lock.
Contains OpenSCAD-files to manipulate the model.
If you print it I would be very happy to see some pictures!
I rounded the edges where the lock slides through. This should make it easier to mount and remove the lock.
The downside is, that rendering now takes significantly longer.
The version with sharp edges is in lockholder_fast_and_easy(v_1_0).scad, the new version is in lockholder.scad.
What you need
include </path/to/lockholder.scad>;). The previous version of the lockholder has sharper edges (which maybe makes sliding the lock inside slightly more difficult) but renders much faster. If you prefer this version, use
completeLockHolderSet()first. Insert your measures from above. Depending on your printer you should add a bit of spacing to some of the settings, as otherwise some holes might be to tight. I added 0.5 mm to
diameterTopTubeand 1 mm to
nutSizeInner. It depends on your printer if you would like to add a bit more or less.
bottomPart. Leave the parameters as they are. After printing the first bottom part, replace the function with
Description for lockholder.scad
Four main modules are provided
topPart()Top part of the lockholder
bottomPart()Bottom part of the lockholder
lockHolderSet()A set of 1 top part and 1 bottom part
completeLockHolderSet()A set of 2 top parts and 2 bottom parts
diameterTopTubeThe diameter of your bike's top tube (or any other tube on which you want to mount the lockholder)
lengthLockLength of the tube where you put the lock through. The longer the less vibrations while riding. On the other hand, if the the tube gets too long it might be clumsy
diameterLockDiameter of the lock (this will be the inner diameter of the part that holds the lock)
nutSizeOuterThe outer diameter of your hexagonal screw nut A/F here
nutSizeInnerDiameter of your screw thread
offsetOffset between upper and lower part of the lockholder. The bigger this value is, the tighter you can screw the lockholder on your bike. However, if offset is getting too big, the material might break while fastening the screw. Normally the lockholders arc would bend down a bit anyway while printing. In this case you can relax and set this value to zero. Otherwise you might want to set it to 1 or 2 mm. If you don't understand the purpose of this variable, try setting it to a large fraction of diameterTopTube and check the result - then you will probably understand it.
screwOffsetShareThis value allows to master the thickness of the screwholes as a share of . At 1, there is no difference to normal thickness, at 0 there is no material to fix the screw. To be on the save side this should be 1 or not too much lower than 1.
