I'm not a pen maker but I've seen some pen making presses online before and always thought the pen presses available look a bit unwieldy with the big press lever etc, when what you really want is control when pressing the parts together, especially with the twist component which has to be pressed in so there is enough of the pen nib showing, with screw in thread you can achieve that.

Anyway this model is what I've come up with, ideally the main body component should be printed with 100% Rectilinear infill for strength and it needs to be printed with ABS or stronger filament again for strength as I've done on this occasion, the remaining components at 60% Rectilinear infill.

I've seen a few video's on pen making and for this project I purchased the very basic of slimline pen kits in a gold finish, there are 5 kits in the pack, I don't have any means of working with wood so for this purpose I designed and 3D printed very basic pen blanks just to show how it works. as far as I know you get the 2 tubes that come with the kit and after rubbing these with sandpaper you apply some CA glue to the tubes and push them into the blanks, then you line the nib part up in the press, the end slider has a hole through it and you use the pin and nut to hold this in place tighten these up finger tight, the slider has a conical hole to house the nib, then the nib blank is held in place with the blank whilst the screw is turned, ensure the blank and nib are inline and use the sacrificial spacer as shown in the photos and then screw in slowly until the nib is seated in the blank.

The clip and end component can then be pressed together, tighten until the clip and end piece are in tight, the clip shouldn't rotate ideally but don't apply too much pressure

The next thing to do is to press in the twisting mechanism, move the end slider along to end position and use the pin and nut to secure in place, and using the sacrificial spacer again against the screw slider and press the twist mechanism in up to the end of the brass piece this is usually enough, take the refill and screw it in then twist to ensure there is enough nib showing.

The final thing to do is push the 2 components together and there you have it, you have a pen.

The 3D printed pen is really tactile to hold and very light, I printed this at 60% Infill ABS, the hole is 7mm but I did have to file the inside a bit for the tubes to slide in easily.

I've included the pen blank files should anyone like to have a go at making a pen without too much expense, these should be printed vertically pointed end up, I printed them at 60% Rectilinear infill with ABS Filament.

There are 2 clamp blocks which can hold a wooden blank whilst it's drilled on the pillar drill(Not tested) and reversing the blocks the press can then be used as a simple vice hence the Title Multi-use press.

I've tried to make it as hardware free as I can but a 5mm x 8mm Grub screw is needed in the bottom of the screw slider to retain the screw thread in place when retracting the slider block.

The press can be screwed down with the 2 countersunk screw holes to a suitable pedestal.

As I've mentioned, I'm not a pen maker but it worked well for me, if there any pen makers who download the model please let me know how you get on with it and any improvements or modifications.

Thanks for Looking.
