A cannon that can’t shoot but is a lamp. You can rotate it in all directions with the base and wheels. It utilizes a regular E26 / E27 socket kit with ring that you can get everywhere. No tools other than a coin are required for the assembly. You can position the cable outlet perfectly while also being able to wind up the cable inside, so you get the optimal cord length.

What you need

• The 3d printed parts
• A E27 (EU) or E26 (US) lamp socket kit that come with a screw-on attachment ring (check the images for a cross section with measurements). You can easily get the sockets with cord and switch on Amazon, Ikea or your local hardware store.
• A LED bulb, preferable short
• Dark colored and non-translucent filament -A coin or similar sized object

Instructions (go along with the images)

• Print all parts
• Insert the socket from below into the shoot
• Screw in the ring from above
• Snap-on the back while using the fuse as orientation helper
• Attach the cannon to the top base with the two wheels, make sure that the slit in the base sits at the back of the cannon so the cable goes in nicely.
• Insert the cable into the bottom base
• Fix the cable in place with the little insert
• Join the two base parts by placing the top on the bottom. Make sure to pay attention to the winding direction of the cable if you want to wind it up a little.
• Insert the base screw from below
• Use the coin to screw it shut
• Optional: Print and glue in the TPU feet

Usage

• Open the wheels a little for vertical rotation
• Use the rotational movement between the two base parts for horizontal rotation.
• Align your outlet so it looks nice and clean
• You can adjust your cable length by winding it up in the base, pay attention to the winding direction and potentially open it up for the job to not damage it.

Print settings Important: Do not use any other light source than LED with this Design. Depending on the strength of your LED certain parts of the print might warm up. Your filament has a certain heat deflection temperature that defines at which temperature deformation might occur. Make sure to build a safe product by verifying that the print is not affected by the amount of heat that your light source emits! If you are uncertain or have little experience in building electrified products, please consult a professional! Usually, a strong LED bulb does not get hotter than 50 degrees Celsius while regular PLA does not deform under 58 degrees Celsius. Those are approximate numbers, and you need to verify that for your own product selection.

Required build volume: 180 x 180 x 180 mm Material usage: 320 g

Material: Filament that can handle the heat that your light source emits. Print direction: files are rotated correctly Support: none for all parts besides the back. For the back use the support type “Tree” and a threshold angle of “30” – default settings will do, it’s only the top center that needs support. Nozzle size: 0,4 mm Line width: 0,4 mm Layer height 0,2 mm Infill: 15% Build plate adhesion type: none for all parts besides the shoot that needs a brim
