Lumo Jr.

Hi there,

some weeks ago our first son was born. And to be honest: this changes everything :)

Being a maker enthusiast, i wanted to make a nice little battery driven lamp in his room.

It should be able to be placed wherever it is needed. Cute looking and 3D printed.

So...

There are a lot of this "Luxo Jr." based projects on thingiverse.

While all of them are at least "O.K.", i wanted it a little bit nicer and at least battery driven.

Screws and nuts at the most used joints. In the end, i've drawn most of the parts again in Fusion360.

This little guy has so many emotions just by using his joints. Whoever at Pixar made this: RESPECT Sir.

• 3D printer to print the parts
• LiPo loader TP4056
• LiPo Battery (https://eckstein-shop.de/LiPo-Akku-Lithium-Ion-Pol...
• Switch (measurement in the picture)
• some small LEDs + Resistor (as bright as you like)
• some perfboard
• wires (same colour as the PLA)
• small screws
• 2 M3 screws and nuts
• Glue

This may look like a lot of stuff, but most of this can be changed with parts you allready have.

The Fusion360 files are included. So you can change the size of the button and the battery.

When choosing the LEDs: a fully loaded LiPo gives you up to 4.2Volts. Choose a matching resistor.

Did you read "some" parts? Thats exactly what you should do.

Print some parts which are jointed without screws and test them if they fit.

I've used Janbex PLA which is quite hard PLA. Everytime you find an object which uses nothing but PLA to be joint together, you should allways trie it, before printing everything.

You may have to play around with some infill or "inner before outer wall" setting.

You can allways change the diameters of all holes in the Fusion Files, too.

Everything was printed on an Anycubic i3 Mega.

Resolution: 0.2

Infill: 70%

If your parts do work, print it all. I had to print 4 tables.

This is quite selfexplaining.

You have to trim the legs of the switch. The switch breaks the circuit between the TP4056 and the LEDs.

Use thin wires and choose long enough wires to the LEDs.

The LEDs can be wired in parallel-mode if you have choosed a matching resistor.

My version has four LEDs, but i'm only using three of them. It is bright enough.

The perfboard is hot-glued to the lampshade.

I don't have a detailed plan about how to put all parts together.

But have a look at the pictures. It is not too hard to figure out. It's the fun part :)

I've used some glue to fix the wires.

The screw at the basement was shortened and fixed with locktide.

The screw at the head was exactly as long as needed.

All files in one ZIP.

It does look nice on your table @work, too ;)

Thank you for reading. Thank you for voting.
