📷 DSLR camera, attachable lens, clickable shutter button, swivel wheel.

Info:

• DSLR camera model (based on Canon EOS 5D Mark II)
• features:
  • attachable lens via thread
  • clickable shutter button, which makes sound (based on great fidget from @kriswillcode)
  • swivel mode dial wheel (with some tension)
  • see through hole (simulates viewfinder very well, you can see above lens nicely)
  • hangers for classic camera straps
• great toy, my son loves it

Dimensions info:

• default 100% scale = about 80% of real camera size
  • if you want real size, scale the model to 125% 
  • I decided to the smaller model because of working tolerances, which will still work on upscaled models (probably with using glue on parts, where there is not that much friction anymore)
    • also smaller model is great for my 3yo kid, and his smaller hands

Parts + print info:

Main big objects 

• camera body:
  • support is recommended for lens hole (see 3mf)
  • 0.2mm layers in general, variable layer height with thinner layers (sample in 3mf) for upper body parts is useful
  • some parts reinforced in 3mf
• lens(es):
  • no supports, inner brim
  • 0.2mm layers in general, slight modification for thread (see 3mf) via variable layer height)
• camera body threaded insert
  • no supports, no brim
  • you will need this to be inserted into camera body (via hole in the bottom)
    • note: thread is not symmetric, the bigger hole should be aiming the outside - close to the lens
  • reason: so the thread is printed horizontally
  • 0.2mm layers

Accessory parts

• dial swivel wheel
  • consists of 2 parts 
    • wheel (used variable layer height for nicer wheel results)
    • round rod (tiny part, designed to make some tension inside. If it is too tight, downscale this part)
  • 0.2mm layers
  • no support
• clickable shutter (producing click sound) 
  • inner mechanism - multiple parts
    • I have published this as separate model, as it is standalone device which can be reused in other models
    • so please download & print the “button-ALL_0.2mm_PLA
      _MK3S_44m.gcode” or 3mf from here
  • camera surface cap
    • print in the same color as camera body
    • it matches the surface curvature of the camera 
    • variable layer height for thin layers on visible parts
    • tiny support needed
  • shutter button cap
    • attachable to inner switch mechanism 
    • variable layer height for thin upper layers 
    • if the connection is too loose, just glue it, if too tight, scale this part up (or ask me, i will upload the same capu with different hole)
    • note: orientate it based on the surface!
    • no support

Assembly:

In general:

• if any connection
  • that should be tight is too loose for you, glue it, or place thin tape on it and try it with that
  • that should be loose, but it is too tight, scale this tiny part down and print again (like the shaft for swivel wheel or shutter button cap)

Swivel wheel:

• put the round rod inside, the cube must be outside
• probably use pliers, to be able to put it inside (by grabbing the 2 parts together), you may use some force
• then just attach wheel on the cube
• try rotating the wheel, it should be slightly tight, from the beginning it may be tigter, but after some time, it will be smoother
• you should be able to remove the rod from inside with pliers, if needed
• you can glue the wheel on the rod

Clickable shutter:

• for the inner mechanism - see linked model
• while you have it still outside - try to put there button cap and surface cover, remember the cap needs to copy the surface
• insert whole mechanism inside (check orientation on the photo!)
• put there surface cover aswell
• and finally attach button cap, if it is too loose, glue it on the inner mechanism

That's it, happy photo shooting :)

  • original camera model downloaed from “Weicheng Jin” page on https://grabcad.com/, where he states, the model is from author “Rhino”
    • i have made transformation into STL,  fixing all the problems in the model and adjusted everything to be perfectly prinable without supports
• shutter button:
  • using my remix based on fidget from @kriswillcode
• lens thread:
  • based on threaded easter egg model from @Tony Youngblood
