The "Wall-Breaker" Modern Catapult & Dynamite Set

🧨 The "Wall-Breaker" Modern Catapult & Dynamite Set 🧨

Updates: Feb 20th 2026, Added another print profile to account for printers that cannot handle a .16mm gap and end up fusing the wall together. The wall gaps are much large, nothing else has changed, no need to print this profile if the original worked for you.

Ready to bring down the house?

Forget boring office toys—it's time for some demolition. This Modern Catapult Set is fully engineered for maximum fun and destruction. Load up a bundle of dynamite, take aim at the breakable brick wall, and let it fly!

💥 Why You Need This on Your Print Bed:

• Print-in-Place Magic: No assembly required! The catapult prints as a single, functional unit. Just pop it off the plate, and it’s ready to fire.
• Includes Breakable Wall: What good is a siege weapon without a target? This set comes with a segmented brick wall designed to shatter satisfyingly on impact.
• PLA Friendly: No exotic materials needed. This design is engineered with strength in mind, so you get excellent range and durability even when printed in standard PLA.
• Custom Ammo: Fires adorable (but deadly) bundles of dynamite.
• Clever Details: The dynamite "wicks" are just short snippets of raw 1.75mm filament! Just press a piece of orange or yellow filament into the top for that perfect look.

🎯 Perfect For:

• Desktop "Office Wars"
• Kids (and big kids) who love destruction
• Late night target practice with your friends

✨Printing Guide:

• Very simple, no supports, use the profile!
• PLA friendly. The catapult is printed with 3 walls and a honeycomb infill to retain shape as much as possible.
• After printing the dynamite, you can insert raw 1.75mm filament as a “wick” for a great look. This is optional.
• The pieces are colored for so they are AMS friendly, but the color isn't necessary for the functionality, works as a single color print too.
• After the brick wall comes off the plate, the seams might be slightly stuck together, just break off the individual wall pieces and you're ready to go!  NOTE If your printer can't handle a 0.16mm gap, print the “separated” profile!

Print, Aim, and FIRE!
