FireSpin - Spin top launcher

I always wanted to design something with gears, as I think mechanical prints are fascinating.

It took a lot of prototypes to get it perfect in every way. But here it is. Attach the spin top. Fire. Challenge your friends for a fun spin. 

Depending of how well you pressed the trigger, you will get an amazing spin. It may require a little practice to get the absolute best spins. 

If it, somehow, gets stuck. Re-attach the spin top, reset and try again.


How to print

It is a fairly easy print, but please follow the assembly instructions carefully. And remember to ensure that your printer + filament is actually capable of printing the small parts. The gears must be clean from any strings and elephant foot.

This model does require high precision from your printer. While the attachment tap will last for hundreds of spins in pla, it may last longer, if you print it in petg.

The launcher can be assembled, using either 2x M3x6mm screws + bolts, or using the included attachments. Screws are fully optional. The snap-fit attachments are also strong, but will not look as nice.

The nuts may be glued in to the case, before assembly. To make the assembly easier. Do not overtighten the screws.
