Description

A fun little print in place crossbow - Perfect for annoying work colleagues or classmates! :P

Features:

Print in place design
Fold out trigger mechanism
Fold out foregrip
Bolts included
Very accurate
Can be extremely powerful

Post Print:

Band Assembly:

Loading:

The easiest way to load the crossbow is to:

Fold the trigger away as if it was just printed
Hold in place with one of your index fingers
With the other hand, pull the rubber band back and hook on the band stop
Release your finger and gently pull the trigger down
Pull out the foregrip
Insert bolt
Fire!

Inserting The Bolts:

There is a very small groove in the very centre of the bolt channel and a corresponding male extrusion on the bolt itself.

This is there to make the bolt sit short of the trigger mechanism when sliding in to place.

This groove is subtle and only there as a guide.

Tip: If you want to get some actual power out of the crossbow, then use a length of TPU instead of a rubber band. This will allow the bow to actually flex and at least doubles the power of the bolt. Do this with caution though, as not only does this make the crossbow potentially dangerous (Not suitable for kids) but it can also significantly weaken the bow after several shots. If you get the tension of the TPU right, then you can achieve a happy medium between power and longevity :) Have fun! :P

I will be releasing some targets to go with this crossbow very soon.

Please follow me for more models and rate and review your printing experience :)

Easy print and fun! I just pulled the rubber band around the end instead of using a piece of filament. Maybe you could add a solid tip to the bolt to weigh the front down and maybe they will fly straighter

Ahhh.....so obvious when you see it! haha Thanks for printing and great tip!

Excellent model and fun idea. unfortunately I had poor bed adhesion for one of the bow arms.

@Zurlingo3D

Oh no! Well I appreciate you not rating the model negatively :) Give it a clean and have another go! :P Thanks for printing!

Replying to @Zurlingo3D :

for sure—definitely not the model’s fault 😁

The side of the crossbow did not print properly. The hole is not even there.

The designer has replied

@Zurlingo3D

This is a bed adhesion issue.. That side of the bow has warped and lifted off the bed during the print. I'd suggest cleaning your build plate with dawn dish soap and hot water and then having another go. I'm sure you'll have much better results with a clean bed :P Thanks for printing! :)

I think it might be your printer

@user_1496843449

I don't know if I put this down or not. lol

The designer has replied

@Zurlingo3D

Yeah, it should pivot down to give you a trigger. Put a flat screw driver in the gap at the rounded end and give it a twist. It should pop down then :)

First run, the sides of the bow came up, but after a good layer of glue, attempt 2, she came out perfect. My son is now having a blast with this mini cross bow. thanks for the cool file!

The designer has replied

@Zurlingo3D

No problem! Glad your Son is enjoying it :) Thank you for printing!

The trigger is very finicky, loading is way to complex. that said, it shoots well, and the print profile is very high quality, so I still give 3 stars despite being kinda useless trigger.

The designer has replied

@Zurlingo3D

Thanks for printing! The trigger is finicky, I can't deny that - This is more a demonstration of a print in place design in a small novelty form factor. Achieving a crossbow style trigger that works as print in place at this scale was actually quite a complex task and I couldn't find a way to make it 'not finicky' and still work as intended lol. Appreciate the feedback :)

bad adhesion (would need a brim for better adhesion)

The designer has replied

@Zurlingo3D

I have printed several of these and the adhesion has been fine.... It does have small parts for a first layer but as long as your bed is clean, it is not an issue. Adding a brim would have the potential to interfere with the intricate joints. I'll add a section about ensuring a clean bed prior to print though! Thanks for printing!
