Tacticool bolt-action Pen

The tactical bolt-action pen is here to give you the ultimate solution for a problem that doesn't exist.

Can't read what you're writing? Slap an ACOG on your pen!

Swaying too much when signing papers? Put a foregrip on that bad boy!

The crushing weight of your parents' disappointment? Add a laser!

From sights over grips to silencers, the tactical pen delivers its bolt-action goodness in exactly your style.

Everything snaps into place, although, depending on your printer's tolerances it might not go back off again.

For everyone too cool for tacticool there is also a plain version.

Things you will need:

• An ordinary boring useless pen. (Alternatively, a small spring and a pen refill.)
• An M3 threaded insert and a 12mm M3 screw to attach the bolt handle to the bolt

It is probably best to print everything oriented as if the pen was standing upright so that the rails fit together nicely.
Supports needed for:

• Barrel, for the opening for the bolt
• Riflestock
• Foregrip
• Pistolgrip
• Acog
• Holo

UPDATE:
I added versions of the attachments with 0.1mm (01) and 0.2mm (02) added tolerance for easier assembly and printing.
