This is combined carriage and extruder for 70mm spaced vertical x-axis. It uses 4 lm8uu bearings and can be removed from the machine without tools or disassembly of the x-axis. With the idler open the hobbed bolt and gear can be removed and cleaned without tools. I've done an extruder test and it rides nicely on the rails, but i wont be able to print anything with it until i build the rest of the machine. The SCAD file is a bit of a mess not everything is derived from the variables at the top.

For this Valentine's Day: a DNA playset. This'll probably only go over well if your significant other is a biologist. But, hey, reproduction is sexy, right?

Thanks to Wikipedia and the hard work of many scientists to measure tiny molecules, this is an accurate 35,000,000:1 scale model of DNA. It's a playset because you print out copies of the four nucleotides (A, T, G, and C) and snap them together into whatever sequence you like.

Not everyone who's into dragons likes Valentine's day or "hearts-and-stuff". Because of that I've made a slight variation of my pet monster.

As requested here's a "not so february"-version of the little pet monster Valentine.

Updated information will be posted in the Instructions below.

Best regards,

I just could not resist. Now your earphone winder is also a handy bottle opener!

The skull is now 2mm thicker than before to make it strong enough to open a bottle.

I ran out of material on the last layer of this print as can be seen from the missing diagonal fill and outline. Despite that it still looks and works great. Enjoy!

This Thing is a coral frag plug that is used when propagating coral (i.e. "fragging") in the saltwater aquarium hobby.

The post for this frag plug has been made removable making it much easier to glue a mounted frag into place in your aquarium as you now don't have to deal with the post being in the way. Rejoice!

Coral fragments are either cut or broken off of the mother colony and then glued to this frag plug using cyanoacrylate gel (superglue). The resulting fragged coral plug is mounted into 14mm eggcrate that is submerged in the saltwater aquarium where it is left until it is either traded with another hobbyist or sold at a frag swap.

Generate it in any size.

Has an experimental feature to include an extra set of inner walls to protect the hinges from the contents. By drawing the hinge lines in a zig zag pattern, plotting time is reduced significantly.

Used to print a MendelMax with a Sells, Prusa, MendelMax, etc.

I saw lucb's thing and I had a die I made in OpenSCAD, so I just combined the two files.

Used openSCAD to cut the heart from the dragon model.

OpenSCAD didn't want to work with the full resolution version of the dragon so I trimmed it down a bit in meshlab. (dragon_lowres_ascii.stl) I used the heart thing thingiverse.com/thing:6190 to clip the heart from the original model. Then clipped the bottom of the heart so it could be used as the heart for the final print.

It's a trophy for the winner!

* Reduced quality (~100k)
* Turned up and bottom
* Some manual added support for faster printing
(no support function needed !
* 65mm tall

The library paratslot.scad allows you to create parametric tslot and accessories.
even mix them in a single render.
Make tslot of any dimension.
30x30, 30x60, 20x40...

2012/02/10 fixed some bugs.

Todo:
add stepper supports,...

Occasionally we hold FIFA 2012 tournaments and I wanted something that the current winner can keep until he/she is dethroned. You can print out the STL with just the FIFA World Cup text or use the openscad file to create your own text. In this case I am giving the trophy as a birthday present and so I've added 'SMITH LEAGUE' onto the back.

Sorry, couldn't help myself :)

Revision for my helicopter motors

I liked the idea Michael521 had in his "Minimalist Spool Holder for MendelMax" thing which this is a derivative of. However, I think I made some improvements on it.

1. These clip very solidly to the extrusions.
2. No hardware! Ok, you do need hardware (the bearing), but there are no bolts in this design.
3. These use even less plastic.

This contains all of the base parts for the printrbot in one tiny tray.

(Extruder, Gears & Clamps Sold Separately. ;) )

Full Tray Fits on a 7" x 6" Build Platform!

2 Smaller trays:
Tray 1of2: 4.7" x 4.5"
Tray 2of2: 4" x 4"

I had some trouble squeezing down tray 1 any smaller... Anyone with smaller then a 5" build platform will need to build Tray #1 on their own...

(Tray a #1 contains: 2 Base's, Bearing Guide & X Motor Mount)

Here is a salt shaker gansgsta, derivative of yzorg's design.
The salt comes out the back of his neck. I wanted to have it come out of his head, but he slouches too much.

It's in progress until I know it prints properly

I was really sad to see that no one had printed Sean Michael Ragan's gömböc (http://www.thingiverse.com/thing:10190)! So I sliced it to make it printable without supports on a ToM, RepRap or similar machine.

Does it work? That is, is it mono-monostatic? Well, mine sure isn't. I printed a pretty small one, 4 cm long and 3 cm tall, and it's fairly content to sit on the flat faces near the top center. I think a bigger one will work better. Let me know if you have better results!

Future changes: Having the seam where it is might be a problem, because the gömböc frequently has to roll over it. Ideally, the seam would be along the ridge, but then I would have to worry about warping.

P.S. How do YOU pronounce "gömböc"? I learned it the Hungarian way, which sounds a little like "GUM-butts". But "GOM-bock" seems to be winning out. But I digress.

This is a parametric version of FdS' flex-box.
You can edit the file using your favorite text editor (notepad, vi, emacs, pico) to change the height, width, and length of the box. Then send the file to your laser cutter and you will have yourself an awesome little box.

edit: v 1.1 some clean-up and bug fixes

A pair of replacements clamps to retain your Techzone Huxley bowden cable using 6-R1/8 straight push-fit pneumatic fast connectors.

All my attempts to retain my ptfe bowden cable before that turned into a failure sooner or later. Now that I use those, I have zero trouble, and it's sooo helpfull for filament unloading/reloading to be able to quickly disconnect the bowden tubing.

Idea came from the ultimaker machine.

The guys at Moving Brands challenged us to help them print their own Chocolate Advent Calendar in a month.

We already knew about the Frostruder, and had most of the parts to build a RepRap Prusa, so the solution seemed obvious. They ordered a Frostruder, and we got busy building their Prusa.

Things got exciting when we tried to mount the Frostruder to the Prusa carriage - it was just too big and bulky!

Luckily, inspiration struck. We stripped down the Frostruder to the bare bones, and used the Prusa to print its own adaptor.

Lo and behold, chocolate printing goodness!

Adapt your lovejoy connector to your Nema 17 5mm rod motor. I was sent the wrong one so took the opportunity to create the Love Joy 5mm coupler for the World. Fits perfectly on the 5mm Nema 17 Stepper motors. Fits a M6 Nut and Screw.

This is a tribute for our teacher Obijuan ( thingiverse.com/obijuan ) that is among the ones that introduced me to the world of 3d printing.

It is a custom Wade extruder gear that has some Rebel Alliance symbol as holes on it.

I've found that the x idler pulley tends to ride up against the top y carriage wood. This creates noise and other problems.

There are bearing and belt holders and all manner of x axis improvements but I've yet to see one to fix this. The idler rides up due to the belt being pulled up to mesh with the x carriage belt teeth.

My solution is to customise the teethes position to match the belts natural path.

This is based off of Joakim's x follower openSCAD file so it can match its customization for a perfect x axis sliding action, print his and mine as they replace 2 separate parts.

All comments and suggestions welcomed, heck just comment

This is a remake of the bunny trouble game, which had some hard time printing for me due to the angle of the ears. Also, I wanted the bunny to be a but more chunky in relation to the hex base.
