//Italian company 'Bikee' designed a mid-drive they called modestly "The lightest". It is positioned in front of the chainring. This is an interesting design as it doesn't need a special frame and its installation is cleaner than others second mount mid-drives. Though they did not invent the system well proved before by the 'powerplay' motor sold by Canadian 'Rocky mountain' company and designed by 'Propulsion Powercycle company'. Uuuh, seems that some mid-drive sellers have difficulties to create discriminating names, just to make web search the most difficult possible ?

// Modifs 2018-2020 by Pierre ROUZEAU AKA PRZ
|
||||
// License GPL V3
|
||||
//Revised: Dec 2018, Nov 2019, Dec 2019, Feb 2020, Dec 2020
|
||||
//Feb. 2020 Improved torso with proper camber, shoulder blades protrusion and better neck junction, more leg parameters (to view amplitude in a fairing), removed pedalling animation.
|
||||
//Jan 2021, neck and head bending
|
||||
|
||||
//while the 'reference head size is fixed, now head have some proportionality to size,say head size is sizeRatio^0.4
|
||||
//Limb and body size are sizeRatio^0.6
|
||||
//This improved proportions on all sizes and small sizes resemble more children than dwarf
|
||||
//Children are not reduced adults, they have different proportions
|
||||
//Feet size is proportional to leg length
|
||||
//Unfortunately, this did increased the calculation time, now around 5 seconds on an old desktop
|
||||
//You can adjust the height (without helmet and shoes).
|
||||
//Leg/torso proportion is now adjustable
|
||||
//More realistic shoe shape
|
||||
//The rider is not completely accurate on anthropometric viewpoint as his/her articulations are in the middle of the limbs, which is far from the reality and troubles dimensions whith folded limbs, which is a common problem in posable models. Very surprisingly, this is the only posable model I found on OpenSCAD. This model was taken from the openbike site (http://en.openbike.org/wiki/OpenSCAD), with corrections of angles errors sign and foot articulation center. I did extended modifications to improve the anthropometric proportions. His/her dimensions are now proportional to head size as common practice. It can be taller or smaller with a fixed head size and articulation are repositioned based upon that.
|
||||
//There is some unchecked attempt to correct the misplaced hip articulation (modified leg length when rotating it)
|
||||
//Also, its design is now adimensional and you can use whatever unit you wish, just giving reference head size and whole size in these units.
|
||||
//This model was itself got from thingiverse model designed as a groom of a wedding cake topper, so no surprise this was not the most accurate human proportions! The initial author may be surprised by what we made from its 3D printed model even if few (if any) of the original code survived the evolution.
|
||||
//There was a very detailed and accurate project for human models (based on bones), but unfortunately not finished here: https://github.com/davidson16807/relativity.scad/wiki/Human-Body
|
||||
//Basing articulations on skeleton is the only way to have accurate dimensions when flexing limbs, but you shall fill in flesh after and that is complex with OpenScad.

//OpenSCAD library modules - written from scratch -
|
||||
// (c) Pierre ROUZEAU(aka PRZ)2015-2021 Licence: LGPL V3
|
||||
// Rev. 7 may 2017 : corrected ldupln function, which was making wrong count, so wrong tenons/slots
|
||||
// Rev 2021: Add profiles, misc. modifications, add 'dark' color.
|
||||
/*OpenSCAD primitives gives a priority to z axis, which needs a lot of subsequent rotations. So, you quickly find yourself lost between your axis, which have been swapped by the rotations. That drive for complex objects to build them on a X/Y plane, then to rotate the ensemble. It is tedious and unpractical.
|
||||
Also, OpenSCAD is using a lot of brackets, which are hard to get on some non-QWERTY keyboards.
|
||||
This library is aimed to ease openSCAD programming and improve readability. Also, primitive names are short. This is not the todays trend, but I find it useful, whithout real penalty.
|
||||
So in the proposed library:
|
||||
a) Nearly all primitives could be used for all three axis. This is simply done by having the axis name being the last letter of the primitive (primx, primy, primz...).
|
||||
b) The translation parameters are part of most primitive (not all)
|
||||
c) You could use negative extrusion and where physically sound, negative dimensions.
|
||||
d) Setting the main dimension parameter negative will center the extrusion, saving the 'CENTER' parameter - for dimensions which could not be physically negative (a diameter...)
|
||||
e) No vector use, so no brackets
|
||||
With that, you have the primitive and associated movements done in one go. Designed for my own purpose, I find that useful and a wrist saver.

// Beware of the axis name. The first axis is the direction of propagation of the slots/tenon
|

// The second axis name is the second plane axis, slot plate wise. This is done to have the same name for the connecting modules, hence, the slotxy will be in an horizontal plate, with propagation in x, while the connecting tenonxy will be for a vertical plate, oriented on x
|
||||
// library is yet limited to xy and zx combos. Use rotations for other axis
|
||||
// As the slots are holes, the slot module is not only a primive but also an operator, so it COULD be used to MODIFY your plate objects. The location coordinates are the last two parameters (x,y or x,z). Typical use will be slotxy(slotlength, interval, tlength, thktenonplate,x,y) myplate(); Alternatively, if not used as an operator, it just creates the holes.
|
||||
//You shall define the 'cutplay' and 'bithole' parameters (look configuration file) to take into account the width of the laser cut or diameter of the bit. The global holeplay variable will so be set to a negative value equalling the laset beam cut diameter (approx 0.2mm diameter), while doing the exportation to dxf files. Such play make the slots invisibles in your model (the slots are smaller than the tenons), if you are not defining a protrusion.
|
||||
// So, during the development of your model, a positive value for holeplay shall be defined (1~2). Note that the visible play is double in length than in width. This is normal, as the plate thickness will not be affected by the cut.
|
||||
//Neither the slot nor the tenon are centered. Negative thicknesses or negative length could be used, but with caution.

||||

Are you playing around with airfoils? Better have a fast airfoil data generator at hand. I found some code doing airfoils in this forum, but that wasn't flexible enough as it didn't take advantage of the new vector features of OpenSCAD 2015.So I coded my own little library to always have a fully customizable 4 digit NACA airfoil data generator at hand. What you geta fully parametric library a bunch of usage examples help functionality well documented code (but very tough in the core part) In my next post I'll show how to do objects that sweep smoothly between different airfoil types being freely shifted and rotated in 3D space. Stay tuned.

Sprocket Generator V2 - OpenSCAD by haand001 on Thingiverse: https://www.thingiverse.com/thing:3059422
|
||||
|
||||
Summary:
|
||||
This is a sprocket generator that is designed and coded to be easy to use, even if you are new to OpenSCAD. Customize your own sprocket according to your needs and export it directly to a .stl file. Slice it and print it!For example, you can change:Bore diameterTeeth countPitch, roller diameterToleranceThicknessShaft length and diameterNumber of holes evenly distributedand a lot more...Test it using the Customizer to the right --> !Use PETG or Nylon for best results with 100% infill, many wall layers and concentric filling setting.The code is generously commented and easy to understand for you to make your own adjustments if required by your specific application. All measurements is in millimeters.Enjoy!

This code is based on the code written by *Talon_1* who based his code on the work of

*Aleksejs*. Big thanks for your contributions. The aim of this code is to be easier

understood by folks that are new to OpenSCAD. The rendered sprocket can be downloaded

as a .STL file and 3D-printed directly using any slicing program.
