KV-2 nozzle holder
A stylised KV-2 nozzle holder, built around the Ender 3 V3 KE nozzle, but works with any M6 nozzles. It's designed to sit proudly on your desk and keep your most valuable nozzle safe and ready to go.
Features
- moveable turret
- moveable/tiltable gun; nozzle snaps in place
- wheels behind the tracks for movement on soft surfaces (optional)
- simplified details, specifically made for easy, quality print
- no supports required, the model comes pre-supported (turret and wheels, use the prepared tabs to pull them off; the support z distance is 0.25mm)
- printed in parts, made for easy assembly: body, rollers, tracks, gun mount, turret and center pin (connects the body and the turret)
- no hardware required! The big parts are snap in place, and the rollers are fixed with 2 pieces of filament (2 35mm pieces or 4 smaller ones), that get covered with the 4 pins
Design notes
- 75x40x35mm, roughly 1:90 scale
- hex gun socket sized to hold M6 nozzles, designed around the Ender 3 V3 KE nozzle
BEFORE PRINTING!
Print the gun mount, and check how the nozzle fits inside. According to that, scale the rest of the tank. Assuming a well calibrated printer, no scaling should be done.
Print settings
- material: personal preference (Sunlu PLA+/2.0 , Grey, Black, Olive)
- layer height: 0.20mm
- infill: 10% (cubic)
- walls: 2
- wall printing sequence: outer-inner (important!)
- supports: no
- brim: depending on the 1st layer your printer lays
- print orientation: print as given
- tolerances: typical FDM tolerance, slightly looser 0.25mm
- turret modifier (7mm tall): 40% infill, 4 walls
Assembly
- print the parts
- remove the supports by the tabs (turret and wheels - if printed)
- snap the gun mount into the turret, aligning the ridges with the pins
- insert the nozzle into the hexagonal hole of the gun mount
- snap the center pin into the turret and press the assembly into the body
- insert (straightened) filament pieces thru the rollers and the body, leaving about 2mm on each side
- push the 4 pins to cover the filament ends
- press the tracks on the rollers (they have been oriented so there is the possibility of using the bed's texture as the front of the tracks)
