As promised, the model telescopic lens tutorial. These were made for to look like Rabbit’s original goggles but this technique could easily be used in different combinations and lengths for, say, Delilah’s goggles, Monocle’s Monocle, fanbot/fangineer accessories, even a tiny telescope. Go crazy. Putting it under a readmore as it’s going to be reasonably lengthy.

What you’ll need: 

Black and Metallic Paint - I find acrylic works best for an older, more distressed finish but if you want a brand-new effect, spray paint works well.

Assorted plastic bottle caps & lids - These will make up the barrel of your lens. You’ll want to find caps of roughly the same height if you want a more uniform look; I like the effect created by having mismatched lengths.  

Goggles -  Just a standard, affordable pair of costume goggles work for this tutorial, you can buy them for under £10 on amazon.

Pipe Cap - This is optional, I wanted to be able to take the long lens off the goggles instead of modifying them permanently. You’ll need one of the same diameter as the lens caps on the goggles - the standard diameter is 50mm. 

PVA Glue - This helps prevent the paint being scratched or worn off.

Scissors, craft knife - Not vital unless you want to customise any of your pieces.

Hot glue gun - If you don’t have one, superglue works too. 

  1. Gather your lens pieces - Use whatever you can find. I experimented with about 20 different lids and caps and tubs. I ended up using a Yazoo lid, a medicine measuring cup, and a drinks bottle lid, on top of a pipe cap. Make sure you wash them thoroughly before use, particularly if they had food or medicine in them.Plastic would be better than metal, it’s lighter and easier to work with, but metal works too.
  2. Arrange them how you want them -Take some time to try different arrangements and combinations. Biggest to smallest is most common but you’re making, for example, Delilah Moreau goggles you might want to experiment.
  3. Hot glue them together. I find the easiest way to do this is to squirt a good amount of hot glue around the inside edge of each piece, and quickly setting it down into place. Hold it there until the glue oozes down and sets.if any seeps outside, quickly wipe it away before it hardens; if there’s some residue, don’t worry, it’ll add to the overall mechanical effect. Be careful with your glue gun, it hurts like all hell if you get it on your hands. When gluing the lens piece to the pipe cap or lens cap, be careful and make sure that no glue gets into the thread, or you could have difficulty screwing it back into place.
  4. Paint it black - you might need two coats for full coverage. This will serve as a base for the metallic colour.
  5. Paint it metallic - I’d use a sponge instead of a brush for this, it gives a much more realistic, old-metal effect. Mix a little of your metallic colour with your black paint, and stipple it over the black. once that’s dry, go in with your original metallic colour over it. Add details with a thin paintbrush if you’re going to do the swirls on Rabbit’s goggles.
  6. Varnish  - Once your metallic paint is completely dry, paint over it with PVA glue. Try and avoid any big blobs; a thin coat will do. This will help prevent the paint from being rubbed off.
  7. Voila, you have a super snazzy model telescopic lens!


  • You might want to paint the ‘lens’ to match the other; I actually filled mine in with hot glue because I didn’t like the shape of the lid, then painted over it with dark blue nail polish.
  • Visibility is basically zero if you’re planning on wearing them over your eyes. It’s more for show than practicality.
  • I ended up finishing the top end  with a rim made from a milk bottle cap.
  • Be careful if you’re using a hot-glue gun or craft knife. Seriously.
  • Though this isn’t perfectly accurate to what Rabbit’s goggles look like, I’m pleased with them. Don’t try and perfectly replicate other people’s designs, do what you like.
  • These are ideal if you don’t want to spend a huge amount on goggles, or just want to make some fairly cheaply.
  • If you’re electrically minded and wanted to do an exact replica of Rabbit’s, you could wire up a small LED to go in the end and leave it clear instead of painting over it.
  • Hot glue can also be used to create a cool welded-metal effect, if that’s what you’re going for.
  • This one can be screwed off and the original lens replaced, meaning the telescopic lens can go on either eyepiece.

Hope this is somewhat helpful - if you’ve got any questions, drop me an ask and I’ll do my best to help you out.
