    @Geof, I included the STEP file with the Thingiverse listing. I will post the A360 link here. https://a360.co/2JFpi1O

    File can be downloaded in a number of formats including full 3D source files.

    Here is one that is for Nozzles only https://a360.co/2w989eG

    Needed a sponge dish so I printed one instead of buying one.

    10 second video.

    This was the following model, https://www.thingiverse.com/thing:857116 The PETG I used is Hatchbox and printed about 5°C too cool as there is a small bit of stringing in the print.

    20180625_135810.png 20180625_135902.png I have a few 20" box fans scattered around all seem to have one broken foot, so I spent a few hours modeling up a foot and printing it. Works perfect. The model is located here: https://www.thingiverse.com/thing:2977438
    If you want to play with it the Fusion 360 file is located here: https://a360.co/2tvc1mH

    Printed at 0.20 layer height, in PLA, with supports.

    Another tool, this time a Kitchen tool. A fixed angle knife sharpener. Printed in Natural and Black PLA

    20181010_140937.png

    An Apex style whetstone is held in place by this section, made up of two PLA printed brackets, a steel compressions spring and an 8 mm optical rail.

    20181010_141005.png

    The adjustable end can be raised or lowered to set the knife edge bevel. the range on this one is 15° to 30°. Typical kitchen knives use a 20° double bevel (both sides).

    20181010_141038.png

    This spring is used to make quick changes for the whetstones (Apex style with plastic or aluminum backing).

    20181010_141238.png

    The adjustable end uses an 8 mm optical rail and an 8 mm eye-bushing

    20181010_141249.png

    The blade is held in place by neodymium magnets, but the black cross can also be used to clamp the blade in place.

    20181010_141309.png

    A better view of the in place magnets.

    20181010_141402.png

    Everything is mounted onto an 11" x 16" wooden cutting board. All parts minus the rails (already owned) and the magnets were purchased from Amazon, including the cutting board. Other parts come from Banggood.com.

    Credit for the model belongs to someone on Thingiverse, https://www.thingiverse.com/thing:2613594. A few parts were modified to allow for insertion of magnets.

    I should have mentioned , it is a spoke tensiometer. I updated all files to take care of a couple of minor issues.

    Printed with cheap Amazon PETG, 0.60 mm nozzle, 0.24 mm layer height, 25% hexagonal infill, 3 perimeters and 5 bottom and top layers.

    Nice, but I don't see how you would actually use the tool. Photo please.

    You do know what it is, correct?

    Once you build your wheel, you would use this tool to verify that the spoke tension is nearly identical on all spokes that originate from the same side of the hub. It you have a spoke at a very know tension, you could of course calibrate the tool itself to reach a set tension level.

    It does look different from the others I have seen, but I "get" how this one is intended to work :)

    This is a derivative of the tool DT-Swiss sells.

    Since I have not done bicycle work, I am a bit clueless as to how the tool fits onto the spoke. I get what you say about using it to verify the spoke tensions.

    I basically works like all tensiometers, in this case the spoke sits on the two outside bolt heads, while the third tries to deform the spoke, you actually measure this deformation/curve (that is then converted to tension in newton meters using a chart if you have calibrated the tool)

    Let me see if I have this right. You first squeeze the tool. Then you position the spoke as described above. Then you release the grip of the tool so that it can deform the spoke and measure the tension in the process. Does that sound about right?
