Little Pumpkins

Nine different little low poly pumpkins ready to be printed for Halloween. Included are: Chompy, Slurpy, Crushy, Piercy, Slicey, Crunchy, Munchy, Smoochy and Squashy

They print quick without any support.

They can be stacked by snapping them together. LED lights can be put in them through the bottom.

Use single little pumpkins as decorations or stack them together then you can have them as a tower or hang them up.

Want to print them bigger and use a torch light with them? – Here is something for it: http://www.thingiverse.com/thing:1091056

Flexing battery holders with integrated spring

For my electronic projects I often need battery holders of various size and for different number of cells: single, multiple cells in parallel or in series, or serial lithium-ion type cells with connectors for balanced charging between the cells.

So the project here was to generate fully parametrized, printable battery holders for cylindrical cells of arbitrary size and number. The additional challenge for me was to have the battery sit firmly in the holder without the use of the metallic spring that is usually found at the minus pole. In this design the metallic spring is replaced by a flexible printed curled structure, which presses the contacts firmly to the battery. This plastic spring flexes about 1 – 2mm, which is just what’s needed to comfortably insert and remove the cells.

The contacts for the plus and minus pole can easily be made by a few windings of the uninsulated ends of the connecting wires. Each battery compartment contains are several holes to the outside as well ad to the neighboring compartments, through which connecting wires can be passed for easy configuring of parallel, serial or balanced-serial battery packs. Also, on the bottom of the case, there are longitudinal and traversal wire channels, which can be used for assing wires outside the case.

Given that the printed plastic spring needs to be flexible, ABS is the material of choice here. Also, I use a some „ABS slur“ (mixture of ABS and acetone) to cover and insulate the otherwise exposed outer part of the pole connectors.
In addition to the SCAD source file, I have added STL files for 1/2/3/4 cells of type AA, AAA, 18650(Li-Ion), as well as single cell versions for 18650P (protected Li-Ion), CR123A (aka 16340) and C (this one is untested yet, as I don’t have any C-cell around here).

Of course, you can also just use these battery holders without any wiring to serve as battery cases, for carrying your spare batteries around. But for this, you should also have a look at my battery caps

Update 2014-09-17: Upon request of user wohenzhuce I have also added STL files for 26650 type LiFePo Cells. These are still untested. They were produced in OpenScad with the call:
flexbatter(n=n,l=65.7,d=26.4,hf=0.72,shd=3,eps=0.28);

Update 2015-04-10: Upon request of user h4wk3y I have now uploaded extra long versions (70mm) needed for some protected 18650 cells, these are named flexbatter18700xN.stl._

Update 2015-07-25: I just published a new version of this project which supports multi-cell compartments housing 2 or 3 cells in a row:

Update

For those who have trouble slicing the gnomon, I ran the files through netfabb and re-uploaded them as:
— Gnomon_Southern_NETFABBED.stl
— Gnomon_Northen_NETFABBED.stl
Let me know in the comments if they don’t still behave nicely with your slicer.

If you wish to print the gnomon in two halves :
— Gnomon_Northen_half_1_of_2.STL
— Gnomon_Northen_half_1_of_2.STL
They should fit on a 100×100 platform. (Thanks Zarlor for building these two files and fixing them ! )

Tadam !
A Sundial displaying the time inside its shadow, with actual digits ! There is a tiny bit of magic inside…

No batteries, no motor, no electronics… It’s all just a really super-fancy shadow show. The shape of the sundial has been mathematically designed to only let through the right sunrays at the right time/angle. This allows to display the actual time with sunlit digits inside the sundial’s shadow.

The sundial displays time (with actual digits !!) from 10:00 until 16:00, updating every 20 minutes.
You can precisely adjust the displayed time simply by rotating the gnomon (the magic box that displays time). So you can even adjust for Daylight Saving Time.

You’ll also need :
— an (empty !) jam jar
— 3x M6 screws, flat head, length = 20 mm
— 1x M6 screw, flat head, length = 50 mm
— 4x M6 nuts
— 4x M6 washer, outside diameter < 14mm

Tadam !
Un cadran solaire qui affiche l’heure dans son ombre avec des vrais chiffres ! C’est un peu magique.

Sans piles, sans moteur, sans électronique, etc… Il s’agit juste d’ombres chinoises très compliquées. La forme du cadran solaire a mathématiquement conçue pour laisser passer uniquement les bons rayons du soleil au bon moment/angle. Cela permet d’afficher l’heure en chiffres lumineux à l’intérieur de l’ombre du cadran solaire.

Le cadran solaire affiche l’heure (avec des vrais chiffres !!) de 10:00 a 16:00 toutes les 20 minutes.
On peut ajuster l’heure en tournant le gnomon (la boite magique qui affiche l’heure) sur lui même, par exemple pour passer de l’heure d’été à l’heure d’hivers.

Vous aurez aussi besoin de :
— un pot de confiture (vide !)
— 3x vis de taille M6, a tete plate, longueur = 20 mm
— 1x vis de taille M6, a tete plate, longueur = 50 mm
— 4x boulon de taille M6
— 4x rondelles de taille M6 diametre exterieur < 14mm

Modified in Windows 10 3D Builder, made the 2 slots for the HDMI/Power Plugs wider as the provided ones in the original were way to narrow for me.

REMOVED cut-outs for cleaner prints and not bombarding the poor printer with retractions. 😉

Made the clip more flexible and replaceable, because the fixed one (one solid cable clip) broke the first time in use.
Make sure you print them as provided (don’t rotate), so the print lines support the clip’s bend direction, otherwise the bending could separate the layers!

I wanted a place where I could store my spare/currently unused Fanatec wheel but did not want to just lean it against or mount it onto a wall.

So I’ve tried to create a stand similar to some of those headphone stands you can find here as well.

I have used the Fanatec wall mount adapter by blazze11 (see remix section) and attached it onto a self-made stand which was done in Fusion 360. Not knowing how sturdy the end result would be in PLA I have made it relatively thick and used 20% infill.
The main stand’s pillar is tilted back so the wheel’s center of gravity is a little more towards the back as well and the whole thing isn’t too front-heavy and won’t easily be tipped over.

The end result seems fine overall but as always feel free to modify it – please post it as a remix though, I am curious about your ideas as well!

Printing with the Anycubic Mega-S I had to pretty much max out the maximum build volume, so I had no more space for brim or skirt – adjust your slicer settings accordingly or use the 3mf file to scale the stand itself a little if you have to. Don’t forget to move the quick release mount to an appropriate position if you modify the stand, though.
I have made the stand the way it is so scaling it only in eg. Z direction won’t be too noticeable.

STL: one object, print this if you do not have to make size adjustments
3MF: multiple objects, scale down the stand if you have to, move the quick release mount to the new position and save as single object/merged to print

Despite its size the print only took about 7 hours.

Oh, the hole at the back is for storing the allen wrench / hex key that is needed for the CSL Elite wheel. I should have made a second hole to store the screw as well, but I noticed it tends to slip out of the semi quick release mechanism after everything was done … 😉

Fanatec CSL Elite Base Rev LED Dimming Plate

It’s great to have such bright LEDs. However I mostly don’t do manual shifting, so they are drawing too much attention. So I’ve designed this Revolution LED Dimming Plate.

The amount of dimming is directly related to your choice of filament, just scale the STL in Z direction to accommodate for that.

I printed this using Redline Filament Glitzer PLA Eisengrau.
I have bought M6x10 screws in black, because standard philips screwheads in shiny silver just didn’t fit aesthetically.

I have modified the box to work with magnets, because I didn’t trust the printed rod, knowing how my printer performs with those from previous prints. 😉
