Strong Reversible Pocket Ratchet Driver - Upgraded by Kwiatens

This is the new, upgraded Pocket Ratchet R2 - A tool, not a toy.

No hardware required - ~1.5 hours to print - only 33g of filament (with AMS)

The Pocket Ratchet is now even more durable and useful!

What's new:

• A better mechanism for switching the ratchet direction (switching is now smooth and snappy, requires less force).
• The lever is snap fit, glue is not required anymore! This makes for easier maintenance and assembly.
• Reinforced lever shaft - More surface area, optimized for FDM printing.
• All parts have a much better fit than before, resulting in a more sturdy, reliable and durable tool.
• Now the lever does not wiggle around freely when in the “lock” position of the ratchet.
• A sprocket that can hold a 4mm precision bit in now available.
• New bigger screw for easier assembly/disassembly + it is flush with the rest of the casing.
• Changed the lever orientation for easier and more convenient switching.
• Ratcheting action now requires less force to engage.
• Improved sprocket design.
• Bigger 6x3 magnets can be installed (only when using the sprocket for 6.35mm (¼") bits.)
• Better ergonomics.
• Optimized print profile for more strength, less waste and faster printing.

Yeah, quite a bit :p

Overview of the project:

I wanted to print a reversible ratcheting driver but all the designs out there were not strong enough.

So I went and designed Pocket Ratchet R1 with “It needs to be strong and just work” in mind :)
Now it's time for an even stronger and refined one!

Here's a video showcasing what Pocket Ratchet R2 can do!

As you saw, it passed my little stress test like it's nothing :) - It is worth to mention that the holes were not pre-drilled! The driver shown in the video is printed only using regular PLA.

On top of that, it doesn't require additional hardware (the magnet is optional, however I highly recommend installing it).

You can set the lever into three positions: screwing, unscrewing and ratchet lock.

Printing guide:

• Clean your plate before printing!
• You can print it in PLA, it will work just fine (that is what I printed it out of but if you want extra strength you can use ABS/ASA, PET-CF, PA or even PPA-CF. If you do, please share the results! I'm just curious how far this new design can be pushed :p)
• Textured PEI Plate recommended.
• ≤0.4mm nozzle recommended.
• If you don't have an AMS, you can select a non-AMS profile - you will still have the aesthetic features visible.

Assembly instruction:

How to use:

You can change the direction of the ratchet by rotating the lever 45 degrees until you hear a click.

When not in use, please set the lever to the middle position (Lock) to avoid permanently bending the claws inside.

How I designed it:

As always, some iterations were needed, but I enjoyed the process :)

I tried to improve the design as much as I can, but if you have any ideas on how to improve the design, feel free to DM me!

Also, I would be very happy if you review both the model and print profile - it really helps a lot in improving my models and the MakerWorld experience :)

If you would like to, you can check out my other designs too!
