Description

My latest design - A useful print in place Bi-Directional Ratchet Driver. Strong and durable, ratchet mechanism fully tested.


Prints fully assembled and working, with a comfortable ridged and knurled design.

 

Fit a driver bit to tighten or loosen screws etc. Just flip the bit to the opposite end for reverse direction. Recommend using an extension for easier fitting and removal of bit.

Uses just 29g of filament.


Recommend printing in PETG for long term durability, will also add a tested PLA profile

 

Can also be used as a fidget roller, making a satisfying clicking noise with each twist.

My first attempt spaghetti'd, so this a brim and isn't really safe for printing from the app. The PLA version works, but the ratchet is very heavy and is neither useful as a screwdriver, nor fun as a fidget.

Hi there, this sounds like you are getting some over extrusion, the ratchet is light in pla (even lighter in petg) I have tested with regular, and matte bambu pla, and petg basic. Also it should grip the bits but not that tight. I do have an idea to improve the tool bit holder though. Otherwise are you using a different brand filament, and is it stiffer?

Replying to @ThePrintsmith :
Bambu PLA Basic on an A1M, your profile with a brim. Attached is the cross section leftovers from my spaghetti attempt, maybe I'm just unlucky?

Very strange! Thanks for sending that over. I've had the odd comment saying the opposite too and that bits are held too loose, so I wonder if it's the difference in auto cal results. I'll see if I can make the design a bit more robust toward differing tolerances

Turned out perfectly, the top layer is smooth and even and the outer perimeter is practically flawless.
