3D Printing Toolbox¶

This plugin collects the usual fixes for shapes that are hard to print, as tools under Print on the rail. It is on by default.

Using a tool¶

You can also pick the tool first, click the faces and press Enter. Each tool adds an ordinary step to the History.

Each step has a Build direction, the way your printer stacks layers. It is taken from Build dir in Overhang, +Z unless you set another there.

Tool	Select	What it does
Teardrop	the inside face of a sideways hole	gives the hole a pointed roof that prints without support
Roof Bridge	the inside face of a sideways hole	squares the top of the hole
Counterbore Bridge	the flat floor of a counterbore	layers the ceiling of a screw recess so it bridges
Sacrificial Layer	a hole's inside face, or the face it opens onto	closes the hole with a thin layer you drill out after printing
Thread-Forming Ribs	the inside face of a screw hole	adds ribs a screw cuts its own thread into
Zip-Tie Channel	the face to cut a channel under	cuts a loop for a zip tie
Elephant-Foot Chamfer	the body, or its bottom face	chamfers the bottom edge, 0.4 mm, against a squashed first layer
Vertical Edge Fillet	the body	rounds the edges that run along the build direction, 2 mm

Bed Fit Check and Printability come with this plugin too.
