This is a pavise as used in Japan during the Sengoku Jidai - the age of the country at war. Pavises were used primarily during sieges, but also figured in some open battles. They were carried by bowmen and arquebusiers alike. This one carries the Takeda-clan crest on the front, and has a working, hinged support at the back.

I was tired of adjusting my extruder idler block for proper tension. I think that it would be much easier to adjust tension if I have an easy-grip nut cap. So here it is!

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.

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

Fully parametric (untested, it works for the parameters as they are set)

The provided STL are fine for a handlebar where the stem clamp measures 46mm, the diameter of the handlebar is 25mm just next to the stem clamp and 22.5mm of diameter some 15mm far away from the clamp.

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,...

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

This is a replacement prosthetic leg for the Walker ( store.makerbot.com/windup-walkers.html ). I started working on this as a replacement for the walker's leg, but have yet to actually print it. If you do print it, please let me know how it fits!

The bicycle of my son...

Has: removable mudguards.
Has (had) not: a way to mount lights on it.

This...

Is: supposed to be screwed on top of the rear mud guard.
Is not: parametric :(

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.

If you've done a lot of soldering lately, then you are familiar with using metallic brillo to clean the tip of your soldering iron. More efficient than a sponge or water, it's a quick and efficient means of cleaning the tip.

I gave away my holder last year, and sadly, Fry's has not carried replacements since. Frustrated after a year, I created my own simplified version.

Thank you to Padawan for the great assist and patience on 8 revisions, for something so simple.

Yep!

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!

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.

make tslot of any width.
10x10
20x20
25x25
30x30
40x40
...

Version 120208.02:
==================
Simplified library, now you pass the model as a parameter.
Added more tslot models.

Version 120208.01:
==================
Added two slots for Wx2W
So now you can print
25x50
30x60

Someone I know is hand-making a game that uses hexagonal pieces. They are using epoxy modelling clay and other miniature figure making materials. When I saw they were cutting the bases by hand I offered to print simple plastic bases for them or make a convenient hexagon "cookie-cutter" so that they would line up with each other better. These pieces are 33mm along a side or 66mm from two opposite points... so they are smaller than Catan pieces (which are 45mm on a side and 90mm across BTW), however as the script is parametric it could be modified to make compatible tiles.

Changes from previous versions:
0.3
- Added proper comments and cleaned up code
- Implemented Parametric Variables
0.2
- switched to using 6 sided conical frustrum
0.1
- First attempt using extruded 6-sided polygon

These are a tight fit for the glowsticks we have, so I shoved my needle nosed pliers in each aperture, rotated, and scraped the holes until the glowsticks fit.

Story to be continued on the blog...

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

Have GLaDOS wrapped around your little finger for science, you monster.

Aperture Science is proud to present the ultimate in portable AI technology. With the Aperture Science portable Genetic Lifeform and Disk Operating System (GLaDOS) you'll always have so much science to do, even on the go!

I really like thingiverse.com/thing:7820# it's an elegant solution to the spool management problem. It's cool the way that it attaches to the top of the machine, taking up a minimum of space.

Sometimes though, the filament has to move at an awkward angle, so I designed this additional bracket to tilt the spool and give the filament an easier time.

This is a cleaned up version of the printed clock we were able to make during Clockathon #2 last weekend. Thank you Makerbot and Bre for setting that up and hosting it, and thank you Ben for all the help, the awesome test print all set up, and the brilliant idea to back off one gear for the power drum.

It was ticking, powered by a weight that would only drop about 9" per twelve hour period, and included printed concentric shafts to support minute and hour hands on the face of the clock.

Here's some video: youtube.com/watch?v=AH4Tg2tIgfg
I had to inflict grievous harm to the code base at the time and have cleaned everything up since. See details below.

My friend needed a measuring cup so I designed one. It's sized based on volume, but otherwise super simple.

cyclone to catch the spray while purging/cleaning an airbrush.

Using a cyclone seems to be the obvious choice for this, but you cannot buy one.

Two OpenSCAD here, one is an evolution of thing 17083 (flat bracelet) and the other adds the texture (knurls in this case).

The inner sizes of the bracelet are 50mm x 60mm and some 32mm tall, the opening is 20mm.

I tried designing a motor mount - which turned out very cool - but ultimately didn't work for my DrawBot. ( thingiverse.co/thing:16725 ) I started this version from scratch and is dead simple and it just works.

I'm 48 minutes (my local time) late for my thing-a-day! Finally, here it is.

It's a flat (boring?) oval (can be perfectly circular too) open (of course, you can close it) asimetrical (thinner at the open side) bracelet (or ring if you make it smaller).

This design is intended to be an envelope to be boolean used (intersection) with other textured designs, we'll see...

Painted a toy tank for wargaming and it clearly needed gattling cannons.

My dishwasher has some pins broken off of the racks. I added a pin to thingiverse.com/thing:16577.

A simplified bottle opener, inspired by Br3ttb's Pocket Coin-Op Bottle Opener. This is a partial step towards a secret project. It's only partially parametric, so watch out. :)
