1-Way Ratchet Screwdrivers [Print In Place] [No Supports]

I've always been fond of sci-fi, that's why I find print-in-place, functional products fascinating. I wanted to tackle a new challenge, and this is the result: a set of ratchet screwdrivers that are useful, strong, and ready to go!

From the printbed to your workbench: it's a print-in-place, no-supports set of screwdrivers for fine to medium duty work, up to M5 screws, bolts and nuts. I've tested and broken three different units with fairly consistent results:

• Max Torque (breaking point):                  7-8 Nm*
• Min Torque (ratcheting):              0.55-0.60 Nm*

*The test prints were made on eSun PLA+, 0.4mm Nozzle, 6 Walls, 25% Infill. Results may vary depending on filament and printing profiles.

Note: This is the free set of ratchet screwdrivers, with separate models for clockwise and counterclockwise use.

You can get the 2-Way Ratchet Screwdriver for only $5 here. It comes with a selector to make it work both ways. It's also print in place, no supports!

Versions: 

There is an arrow and a small dent marking each variant:

• Ratchet Screwdriver Clockwise Short (12mm hole)
• Ratchet Screwdriver Counterclockwise Short (12mm hole)
• Ratchet Screwdriver Clockwise Long (24mm hole)
• Ratchet Screwdriver Counterclockwise Long (24mm hole)

Optional:

• 6x2 mm magnets with some CA glue to fix the magnets in place.
• I recommend applying some lubricant (e.g. lithium grease) through the openings on the sides to prevent the plastic from wearing off.

Printing:

• Once printed, remove or break the runners (small connectors) from the bottom of the print.
   
• This print will have to endure mechanical stress, so don't save on filament here.
  • Nozzle: 0.4 mm
  • Layer height: 0.12mm to 0.20mm
  • Walls: 6 minimums.
  • Infill: at 20% to 25%, Rectilinear.
     
• You'll find a 2mm hole going through the body. It's not a bug, it's a feature! Its purpose is to provide a solid column of walls around this hole to strengthen the vertical axis when applying force.
   
• Make sure your printer can do 0.2mm tolerances. I recommend you test your printer capabilities with my QuBenchy - 3D Printing Torture Test Cube:
   

Feedback is welcome. Cheers!
