3D model description

These files are provided for PERSONAL USE ONLY

The BBHAMMER is a a compact 3D printed repeating crossbow ballester for 12mm, 15mm and 17.2mm (0.68cal ) balls with a quick exchangeable magazine .

The crossbow can be powered by bow arms or rubber bands and equipped with different attachments, foregrips and shoulder stocks.

Differnt materials for the balls can be used like wood, plastic or steel.

Bow arms with up to 130lbs have been successfully tested with recommended filament (PLA+) and print settings.

The design is optimized for a 300mm x 300mm print bed.

Building instructions are included.

Hardware needed for the build is shown in Images.

The assembly is easy but requires some mechanical understanding and accuracy!

Some videos I found of Martin Scherzer who already built the BBHAMMER.

Q: Can I use this model for commercial use?
A: No - I designed this for fun and for the 3d community

Q: What can I do to improve accuracy?
A: Described in the building instructions

Q: Are there building instructions included
A: Yes

Q: What is needed to build this one?
A: Hardware kit is shown in images of this design

Q: Where to buy balls, bow arms, screws, springs etc.?

A: Will see - maybe in the next updates...

Q: Why use rubber around the bow arm?
A: It's to fix the bow and to absurb the energy

3D printing settings

  • The design is optimized for 3D printing with a layer height of 0.2 mm and a print bed of at least 300mm x 300mm!
  • All essential parts can be printed without any support structure!
  • The specified alignment / orientation of the parts on the print bed is crucial for later strength!
  • Recommended Material for this print are PLA+.
  • Some parts (e. g. Trigger, Lock and Lever Splint etc.) are recommended to print with 100% infill.
  • For the best strength and durability, its recommend printing all parts with a wall thickness of 2.25 mm, bottom and top walls thickness of 1.2 - 1.6 mm and infill of at least 30%.
  • Its also recommend printing at a slightly higher hotend temperature than usual.
  • The 3D printer should be well calibrated (extruder steps, flowrate, first layer height).
