Giant Heptagonal Nut with Bolt (Seven-Sides)

This is one of those big hex bolts except its a heptagon. Totally unnecessary but I just think it looks cool. I guess you could put money in it, but I think the bolt is so cool that people will steal the bolt, so you'd lose the money along with the bolt. You can also stack two of the large hep-nuts to make a pen holder lol

This is really just an M12 bolt that's been scaled up 400%. The bolt head and the nut both stand 40mm tall. The shaft part of the bolt is 140mm tall. The blue bolt is actually scaled down to 62.5% and is 25mm tall.

Some printing tips:

• You shouldn't need supports unless you increase the bolt height to 60mm and above (I tried 60mm without supports and it failed badly due to increased overhang of the threads).
• I printed the big set with Prusament Galaxy Black PLA, a layer height of 0.20mm (SPEED), a brim. I recommend a smaller layer height but honestly who really has the time
• I used Prusament PETG Chalky Blue for the smaller bolt and after some breaking in, it's smoother than a freshly buttered double-sided smooth PEI Steel Sheet.
