Full-Scale Water Cannon

Update from January 13, 2026:
 

The print profile has been updated to version 2. The issue with the previously oversized nozzle insert has been fixed. Unfortunately, there was a scaling error that I overlooked.  With this correction, the print profile is now back online.

Description

After receiving so much feedback on my pen holders, a life-size version of the nozzle was also requested several times as a decoration

This version has been massively reinforced in critical areas and expanded with a few parts The adhesive joints should thus withstand a bit more stress Additionally, the proportions of the nozzle have been adjusted

The nozzle consists of several parts that need to be glued together For a realistic result, the following colors should be used (any other combination is of course possible):

• Black → Bambulab PLA Matte Black
• Red → Bambulab PLA Matt Dark Red
• Silver → Bambulab PLA Basic Silver

I use the well-known UHU Hart plastic adhesive

Supports:
The nozzle should be printed with supports so that the nozzle insert can be placed inside

Note:

I explicitly point out that this object is to be regarded as a decorative item

The object is divided into 5 print plates so that it can also be printed on the A1 mini

Those with one of the larger printers can print all black and red elements on one plate each

I recommend printing the nozzle with a 2mm inner brim to make the edges clean Then remove the brim

Enhancements:
If you would like to use the detailed coupling, simply scale the parts of the set to 122.5% size
