# GearHinge
|
|
|
|
|
|
|
|
|
|
GearHinge is an openscad model of a geared hinge. This was developed as part
|
|
|
|
|
of another project, but stands on its own as a part that could be re-used.
|
|

|
|
|
It is designed to be printed in place and without support materials.

|
|
|
Printing is very sensitive to options, and slicing should be inspected to
|
2021-01-14 08:33:52 -05:00
|
|
|
ensure parts have not been connected internally.
|
|
|
|
|
|
|
|
|
|
Chamfer of 45 degrees with a profile shift of -2 has been enough to
|
|
|
|
|
print this in PETG with a layer height of .15mm. These are the defaults.
|
|
|
|
|
|
|
|
|
|
Printing with a rotation higher than 92 degrees is likely to cause the
|
|
|
|
|
gears to be fused as the block tooth may make contact with its counterpart.

## Requirements
|
|
|
|
|
|
|
|
|
|
This model uses the PolyGear library https://github.com/dpellegr/PolyGear
|
|
|
|
|
in order to generate gears and slice them up.

## usage
|
|
|
|
|
|
|
|
|
|
```openscad
|
|
|
|
|
include <GearHinge.scad>
|
|
|
|
|
|
|
|
|
|
$incolor = true;
|
|
|
|
|
|

|
|
|
gear_hinge(width=18,rot=92, door=false);
|

|
|
|
```

## Status/Known Issues
|
|
|
|

|
|
|
Under development, should be vaguely usable.
|
2021-01-10 11:41:28 -05:00
|
|
|
|
|
|
|
|
1. Arms have no mounting holes for general use.
|
|
|
|
|
2. No functions/workflow exists for attaching arms to anything else.
|
|
|
|
|
4. Cannot be assembled or disassembled; must be printed in place.
|
|
|
|
|
5. Helix angle can only do a single "turn". Should be re-written to use sin.
