C-Clamp / G-Clamp Remixed - Better clearances and durability

Notes

Since my poor tolerances of my 3D printer did not allow me to print the thread correctly, I remixed the great 03v2 file from Wilko to fit my needs (thank you for the fusion 360 file !)

Fully compatible with the original author design, the thread is the same, so you can just reprint a stamp if you have already printed the original file. Since, it is minor modifications, the parameters in the fusion 360 file should still work.

This large clearance should work with any well calibrated machine, even cheap one like mine, but if not, you should definitely full check your 3D printer.

I took clamp 03 v2 file as reference presuming it was the last version, if it was not, forgive me.

Print instruction

Follow the original author advices, 0.2 works great, 30% infill minimum, 8 walls is great for the design of the clamp (less top and bottom layers is ok). 80-100% infill on the stamp and platform maybe necessary for maximum durability but I have not tested it yet (30% work for my actual needs).

23/04/2024 edit : users have come up with difficulties for the pad integration, they suggested to warm the pad before assembling. In addition, I will suggest to screw the clamp completely against a hard surface (or empty) to help you assemble the pad. 
For knowledge it is normal for this part to be free of movement (e.g. angle with the bottom plane) but it should stay assembled with the screw.  

List of Changes

V1.0

Stamp thread (see before/after screenshot)

• Offset the thread faces of 0.1 mm (top and bottom).
• Offset the thread edge of 0.15 mm
• Fillet on the edge of this thread and on the corresponding face on the clamp thread for a better durability.

Stamp head (see before/after screenshot)

• Modify the sketch of the revolution of the stamp head (which maintain the platform) for better strenght
• Correction of a mistake on the begining of the thread not allowing a clean finish.

Revision history

Larger clearance for the thread, stronger head. Fully compatible with original design.
