Slack config to standardize different usages of slack/tolerance values.
|
|
|
|
The purpose of this config is to introduce some consistency with how slack values defined in code. E.g. Why is the
|
|
slack value defined as 0.3 in this file, but 0.4 in another? This will also allow model-level adjustments for tighter
|
|
fitting parts, for when it might not convenient to adjust the actual 3d printer (using a 3d printer at a makerspace,
|
|
for example).
|
|
|
|
Some important details:
|
|
- The general philosophy for slack applications in this project is to subtract space from sockets, while not
|
|
modifying the plugs. TODO: enforce this
|
|
- Values are signed. Positive values can be interpreted as how much to remove from the socket along some dimension.
|
|
- This shouldn't be used to compensate for more serious part shrinkage (> +-0.5mm differences)
