Generates Inkscape SVG file containing box components needed to
|
||
|
|
CNC (laser/mill) cut a box with tabbed joints taking kerf and clearance into account

Original Tabbed Box Maker Copyright (C) 2011 elliot white
|
||
|
|
|
||
|
|
Changelog:
|
||
|
|
19/12/2014 Paul Hutchison:
|
||
|
|
- Ability to generate 6, 5, 4, 3 or 2-panel cutouts
|
||
|
|
- Ability to also generate evenly spaced dividers within the box
|
||
|
|
including tabbed joints to box sides and slots to slot into each other
|
||
|
|
|
||
|
|
23/06/2015 by Paul Hutchison:
|
||
|
|
- Updated for Inkscape's 0.91 breaking change (unittouu)
|
||
|
|
|
||
|
|
v0.93 - 15/8/2016 by Paul Hutchison:
|
||
|
|
- Added Hairline option and fixed open box height bug
|
||
|
|
|
||
|
|
v0.94 - 05/01/2017 by Paul Hutchison:
|
||
|
|
- Added option for keying dividers into walls/floor/none
|
||
|
|
|
||
|
|
v0.95 - 2017-04-20 by Jim McBeath
|
||
|
|
- Added optional dimples
|
||
|
|
|
||
|
|
v0.96 - 2017-04-24 by Jim McBeath
|
||
|
|
- Refactored to make box type, tab style, and layout all orthogonal
|
||
|
|
- Added Tab Style option to allow creating waffle-block-style tabs
|
||
|
|
- Made open box size correct based on inner or outer dimension choice
|
||
|
|
- Fixed a few tab bugs
|
||
|
|
|
||
|
|
v0.99 - 2020-06-01 by Paul Hutchison
|
||
|
|
- Preparatory release with Inkscape 1.0 compatibility upgrades (further fixes to come!)
|
||
|
|
- Removed Antisymmetric option as it's broken, kinda pointless and looks weird
|
||
|
|
- Fixed divider issues with Rotate Symmetric
|
||
|
|
- Made individual panels and their keyholes/slots grouped
|
||
|
|
|
||
|
|
v1.0 - 2020-06-17 by Paul Hutchison
|
||
|
|
- Removed clearance parameter, as this was just subtracted from kerf - pointless?
|
||
|
|
- Corrected kerf adjustments for overall box size and divider keyholes
|
||
|
|
- Added dogbone cuts: CNC mills now supported!
|
||
|
|
- Fix for floor/ceiling divider key issue (#17)
|
||
|
|
- Increased max dividers to 20 (#35)
|
||
|
|
|
||
|
|
v1.1 - 2021-08-09 by Paul Hutchison
|
||
|
|
- Fixed for current Inkscape release version 1.1 - thanks to PR from https://github.com/roastedneutrons
