3mm Direct drive extruder compatible with Prusa Mendel and similar printers.

A small and quiet extruder only requiring a three parts rather than the six parts from wades extruder as well as the printrbot extruder mount system. It can also be doubled up with a mirror version for dual nozzle printing.

This is (yes another) filament spool holder. I decided that I wanted one that was like a little Mendel frame - a nice little triangle.

It has a very smooth action and feeds filaments reliably (mine does at least).

The frame vertex is based on the Prusa part with an added hole in the middle and slightly thicker. The hub and spokes that hold the spool are of my own design. Enjoy.

LET'S TRAP THAT MOUSE! I DESIGNED THIS MODEL SO IT CAN BE BUILT ON ANY 3D PRINTER. NO OVERHANGS, JUST PRINT ALL 3 PARTS AND GO! I DO NOT HAVE A 3D PRINTER SO IF YOU ( YES YOU) CAN PRINT THIS ITEM, I WILL SPLIT THE WINNINGS WITH YOU! HOW AMAZING IS THAT, RAPID PROTOTYPING AT IT FINEST! LETS GET THAT MOUSE!!!

PLEASE LET ME KNOW IF YOU BUILD THIS. I WANT FEEDBACK TO MAKE THIS TRAP BETTER! TESTED IT IN SOLIDWORKS AND SHOULD WORK GREAT! ANY OTHER QUESTIONS JUST ASK!

youtube.com/watch?v=PfoC_vY3pdQ

3-4-2010: Thanks to erickphd and his students at Penn. College of Technology we have some modifications to this model. If you have already printed this model, do not attach the Counterweight rail to the Base And tape 2 Quarter to the right side of the Tilt-N-Trap.

ErickPHD Said

"Testing shows a reasonably reliable trigger at 27 grams but the average mouse is 10-25g so my class thought that it needed to be a bit more sensitive"

ADD two quarters and removing the Counter weight rail should give a More sensitive Design. Check out the picture to see the modified design

Here's my totally untested design for entry in Cathal Garvey's Mousetrap challenge.
(Challenge: blog.makerbot.com/2010/03/01/cathal-garveys-mousetrap-design-challenge/ )
(Cathal: thingiverse.com/cathalgarvey )
Thankfully I don't have the vermin problem Cathal does. The downside is that I have neither tame nor wild mice to test this design on.

The idea is to cut out most of the lid from a peanut butter jar and insert this printed lid. Hopefully it will allow the mouse inside to feast on the delicious delicious peanut butter but not let them out. (Who would want to leave a room lined with peanut butter anyhow?)

For design notes about this thing, check out my blog at makerblock.com.

FYI, I think I'm the first one to include a jar of peanut butter as a "part"!

It is a proof of concept of a kind of printable spring. Initially I designed it for using in my Prusa Mendel, because the z axis springs were very difficult to find for me. Then I generalized the idea and parameterized the spring.

These springs conceptually consist of a strip of plastic that is bended. The outer cross section of the spring can be square, hexagonal or octogonal.

The spring parameters are:
* fid (fold inner diameter)
* folds: Number of folds
* th: strip thickness
* Drill: Drill diameter
* Diameter of the outer cross section

Here there is a video of the proof of concept:

At last, the symbol of Star Trek is on Thingiverse! I created this because a friend of mine wanted to dress up as a character from Star Trek, and didn't have the appropriate gear. The clothes are pretty easy to find, but the badge isn't so simple to get a hold of... or at least it wasn't.

The stl seems to skeinforge weirdly, which probably has something to do with the way I joined the two pieces of the badge. Having printed it I can attest to the fact that it prints very well, despite the perilous overhang, which leaves plenty of room for any small electronic bits you might want to insert and try to make the badge do something cool.

Sorry for the rendered image - I haven't printed one out for myself yet.

This is a fun way to demonstrate the surface tension of water.

Makes a boring key an exciting key by adding a skull to it!

A small planetary gears system with a ratio of 4:1 per stage, as many stages as wanted, small, open enclosure to see the gears, and hardware free.

The gears are designed with a circular pitch of 2.5mm and they are also slightly beveled at the tips of the teeth to avoid the need of cleaning the excess of material from the firsts layers.

The OpenSCAD is not parametric, there's only parameters for clearance (set to 0.2), backslash (set to 0.1), pressure angle (set to 22.5), tolerances between nuts and bolts (set to 0.4) and length of the bolts, sometimes referred as rods. Any other change will not work.

To play with the OpenSCAD you will need the following libraries:

Public Domain Involute Parameterized Gears by LeemonBaird
thingiverse.com/thing:5505

Poor man's openscad screw library
thingiverse.com/thing:8796

Knurled surface finishing library
thingiverse.com/thing:9095

The libraries have been included in the ZIP file together with STL files for every single part, build plates for complete sets from 1 to 4 stages, just the crank and upgrade kits from 1 stage to 2, 3 or 4.

I have seen some Knuckles on Thingiverse but none really looks like the original ones, so I designed these. These just print out on the Cupcake and still full sized. If there are any changes you all would like to have on them please let me know and I'll make it happen.

Thanks again for viewing my designs..

Jax

Update: I have noticed that the 1st STL file was tilted on the platform thus making it impossible or at least hard to print without correcting this skew. SO the second file Brass_Knuckles.stl is where the knuckles are set flat on the platform at an angle so the Cupcake can print it at full size. Sorry for any inconveniences this may have caused you all.

Brass is a hard metal, and you might hurt someone! Use these wooden knuckles instead.

These should be considered "art" and in no way should they be used as a weapon.

This is a derivative of the door stop by eagleapex. I made it less tall so it would work better on lower doors. I also made it narrower to print faster and save on plastic.

It's a Mini Disc or Marker for my favorite pastime, Disc Golf. Flies much like a very small Frisbee.

This is a DLP projector-based resin printer that can make very fine 3D prints in record time.

This is a work in progress. Today I plan to begin actual experiments with the resin.

I believe the basic design I am producing here is very suitable, however, the details of the design need changes in almost every part to be ideal. Most importantly, the vat should probably be much shorter, but the whole thing could be made significantly smaller.

I am currently using resin from
Bucktown Polymers:

bucktownpolymers.com/

(You might notice their price for resin is cheaper than some current PLA prices, by volume)

A2Sheds has provided a page with a few helpful resources, as well as the beginnings of his own DLP project:

code.google.com/p/lemoncurry/wiki/main

This is very much a work in progress. Expect more photos and videos to come.

Here's a link to my flickr site documenting this project:

flickr.com/photos/13723140@N04/sets/72157629564335469/

Video of resin cure here:
youtu.be/UVDN2xq575A

Next steps: Experiment with resin. Create working software stack.

Known Issues: Vat is too tall/big, glass may be too weak/thin. Vat probbaly needs a nonstick coating, like silicone or PTFE. Z Axis range is 5", vat is 5", so Z stage cannot quite clear the vat. A2Sheds recommends a heated vat to 50c so the resin flows better...

I love Triffid Hunters "Integrated Z motor mount, frame vertex and rod clamp for Prusa Mendel" thingiverse.com/thing:12151 and brupje's "Reel Holder" thingiverse.com/thing:15224

Decided to add the reel holder supports to the motor mount and design my own top section to hold the 608 bearing.

Modified version of jonaskuehling's x-ends for use with LM10UU/LM10LUU and 10mm z-rod.

I am marking this as work in progress because I haven't mounted this into my mendelmax yet.

This revision includes minor tweaks which necessitated breaking it into 4 parts. Thank you nycdesigner, tbuser, and landru for your helpful suggestion, guidance, and sticking with me til the end.

The recorder is one of the oldest woodwind instruments. In the hands of an experienced player it creates a sound synonymous with Renaissance music. Often used in elementary music classes because of it's ease of operation. With 3D printing everyone can have one of their own to make beautiful music on... or wailing screeches if they never got past "hot crossed buns".

Compact portable key chain/paperweight for portable protection from overbearing papers and key chains that need to have their trap shut. Make sure you don't get caught off guard in those 2 on 1 situations where those papers try to surround you unfairly.

Caution: use at your own risk, not only could this be considered a weapon, but can cause serious damage to stationary and other things...

This is a new and improved drive gear for the upcoming Plastruder MK5. It is backwards compatible with the MK3/MK4 plastruder designs and provides 200% increased push force.

This is a little clamp / clip to attach additional stuff to your Mendel or to any M8 rods. I designed this clamp to keep my fumes filtration cover in place (will be posted here later).
It has a small drilling to screw anything you like on it...

Update, the fixed file has been uploaded, sorry for the prior issues.

Update: Apologies, not sure what happened to the V2 file to make it corrupt, but I will rebuild and re-upload this evening. I have removed it to stop anyone else from wasting their time.

Update: I added setscrew to the motor shaft end. The vibrations would walk the Z axis down slowly. This stops that. I also make it smoother to take advantage of Sprinter's speed.

The old version:
I edited the coupling.scad file to increase the outer diameter and thus wall thickness of the part. I also added hex recesses to capture the nut for the clamping screws.

I had issues with the originals splitting. I think it's because I used PLA (I only use PLA) so you may not need this for ABS.

The Clonedel RepStrap was inspired by the Prusa Mendel (see the related article).

open3dp.me.washington.edu/2011/02/prusa-mendel-and-the-clonedels/

It came about due to necessity of students wanting to build RepRap style machines faster than we could 3D print them. It took about a week outside of class to redesign Prusa parts for mold production. Most of the parts required only minor modifications, but several parts, such as the X-Carriage assembly, required redesign. All modified parts were placed on mold pattern plates to allow for the production of silicone RTV molds.

All of the STL files are now posted here and on GitHub as an Open3DP fork off of the Prusa tree.

github.com/open3dp/PrusaMendel/downloads

They are to be considered Alpha release (and we are already working on some changes). However, we am quite sure that you will be able to use them to print master forms to produce molds (because we have produced molds and we have used the molds to produce RepRaps).

These mold plates represent the current best practice as provided by reprap project, prusa mendel, jnfisher, whosawhatis, rustyspoon1121, etc.

Further, Metrix Create Space has already created molds sets and cast parts. Metrix Create is already making them available.

{P.S. Several people have had trouble with EndStops and XMotor. I uploaded them to NetFabb Beta to fix them. I have uploaded _Fixed versions. Please let me know if these files are better.}

This is V2 of my carabiner thingiverse.com/thing:3131
V2 allows easier printing, and the clasp is in-line with the rest of the body. Makes a great Keychain!!!

One of my friends loves horses and asked me to make a keychain for her based on a drawing she made.
Sorry, no picture of the actual thing, I gave it away as soon as it printed. Everything printed except for the nose hole though.

It's a 3D printable screwdriver handle for 1/4" hex bits.
NEW! - Now with a compartment to store 7 bits

I liked the idea of older Prusa x ends, that use two screws for each rod to fix it, but the implementation was rather weak. With iteration 2's solution (press fit, closed ends) it's a mess to disassemble the x axis, so I thought up a new robust version and since modifying one of the existing files would have taken even more time, I designed it from sratch and added even more upgrades like my clamped LM8UU holders!

Prusa's snap in LM8UU holders have one huge problem: motor- and idler-mount are supported via those holders, so the whole holder can twist unevenly and warp the bearings agains each other. This is avoided with my design.

The rods are fixed using one screw for each, tightening the built in clamps. Their screw heads are easily accessible from below and there are nut traps at the top. I made open end rod holes, to be able to push the rods all through. The system achieves a rock solid fit AND easy adjustability - what else you should need?

The leadscrew nut trap uses two bridges inside instead of a circular hole, so there's no "post-print-processing" (i.e. drilling) necessary in this point.

The design is entirely parametric, so you can even use professional leadscrews like trapezoidal ones with bigger nuts. I additionally attached STLs for use with metric trapezoidal leadscrews TR8x1.5 and nuts of 17mm wrench size (15mm height). For standard Prusa requirements use the "threaded rod" files.

This is an update to my Accessible Wade's Extruder.

The idler is now hinged using an M3 screw.
I have also added support for the central part of the 608 idler so that there is no need to use washers to space the bearing away from the plastic.

I have been using this design for a while now and love it.

Changing filament is a simple as compressing the spring then whipping out the old filament and poking the new one in.

UPDATE: 6 Aug 2011 - Add arcol (cory75 thing:10532) and wildseyed hotend mount options. Im not overly happy with the asymmetry of the arcol option.

CdnRepRap's LM8UU holder was just what I've been looking for - every other holder I've tried has been very fragile for me.
However, it was set up for metric screws and was not in a format I could easily modify.

So here's an SCAD implementation. It's done as a module so it can easily be tacked onto other objects. I put them on Greg's X carriage in about 10 minutes (I'll post this later after I print a test one).

This is a fresh implementation made by just printing one of the original objects, measuring it and bashing it out in SCAD. Enjoy.
