Photo Etch bender

Photo etch bender

In modelling, photo etch is widely used for upgrading models. Often, these parts need to be folded accurately. Tools for this can be bought, but we own a 3d printer so we can print them ourselves.
I designed this model myself.

non-printed parts.

1. bolt m3x20mm
2. nut m3
3. spring from a ballpoint pen
4. 2 pieces of filament 1.75x7 mm

I have attached 3 bases, 1 for M3x20 countersunk head, 
1 for a counterbore head and one for a hex head.

The bolt was inserted into the bottom with super glue

In Prusa Slicer, this is easily changed to a round or hexagonal flat hole.

A 10mm piece of the spring was ground off with a dremel grinding wheel. Then the remaining spring was stretched by hand to fit the ballpoint again.

To gide the cam there are two pieces of filament placed in the two small holes of the bottom.

Happy printing
