Detailed Guide On How To Build Ultimaker 2 Extended Clone

You really want to have an Ultimker 2+ Extended but don't have the money? You support open source and hold a grudge against Ultimaker for going closed source? Well, here is a perfect project for you.
Betrue3d site has a detailed guide on how to make an open source version with all the details you will need.
Great work betrue3d!

3D Printable DIY Rotary Tool aka. Dremel Clone

Makernaut developed and published this great 3d printable rotary tool or Dremel. It looks easy to make even with entry level electronics skills and has three 3d printed enclosure parts.

It is powered by 12V DC motor (listed as 6000 rpm, RS-550S motor, diameter~37mm), it has PWM DC motor controller (3A) and mini chuck / collet set for 3.17mm shaft to hold the tool bits.

Here is the build guide video with a short demonstration:

How To Repair Broken Eyeglasses Frame with 3D Printing

Since I wear eyeglasses since my early childhood, I have broken them may many times. To repair the frame is not easy and replacement is always costly. You can use some superglue or other hacks but it's problematic if the part has shattered in several pieces or you just can't find it.

Matias Mamone published his tutorial on Instructables featuring a easy step-by-step process how to design the broken part and 3d print it to make a solid bridge to fix the frame. Nice! Thank you Matias for this cool tutorial!

How To Repair a Molten Extruder

GuruBrew had an extruder melt down and he made this extensive video guide on how to repair the damage. Very useful learning material.

Here you can see the extruder gear bent out of axis due to heat melting it:

How to repair older version of Printrbot metal heat bed

If you have a problem with some older versions of Printrbot metal heated print bed, Brook demonstrates how to fix it. It looks simple and easy to do even if you are not so experienced.

How to make translucent 3d printed parts transparent?

Do you know the difference between translucent and transparent? I didn't, but I got it after watching this video.
This free webinar will teach you how to get 3d objects optically clean by polishing, buffing, photobleaching, sanding, clear coating and applying other techniques. It is focused on Stratasys VeroClear material but it can be applied on other surfaces to get better finish.

Webinar is presented by Tyler Reid of GoEngineer.

Simple Tutorial on Effective 3D Printed Objects Painting

Here is a great 3d printed model paining tutorial based on real life experiences of Cliff Mellangård. It will show you how to paint your larger printed objects for optimal aesthetic effect with common dyes and simple technique.

Cliff also developed FunBot Pro and FunBot i1 3d printers that are very cheap to make even for the novice builders.

How to Make a PCB with Sharp Metal Rod Attachment

Here is a simple new method on how to make a PCB with your 3d printer. It doesn't use a CNC milling attachment but a simple sharp metal rod attached instead of an extruder which scrapes away permanent marker layer form a standard copper PCB blank.
PCB is then finished in ferric chloride bath.

Video of the process:

Very detailed step-by-step tutorial and .stl for the K8200 rod attachment (you will have to redesign it for other printers):

Design 3D Printed Cranial Plates

Here is a great detailed tutorial by Materialise on how to use their 3-matic software to design custom cranial implants for complex skull and head injuries. Useful for both medical professionals and amateurs.

How to Use Wax to Make Your Parts Waterproof

Instructables user Jubal117 developed this finishing method where he uses wax dipping to make a 3d printed part waterproof. It will make it float or usable as liquid container. Molten wax fills the cracks between layers and makes it into full envelope.

Functional 3D Printed Stepper Motor

Proto G published his detailed guide on how to build a 3d printed stepper motor. It is probably not as good as standard ones but it looks very usable for simpler projects.

You will need an Arduino, copper wire, magnets and other non-printable parts but you probably guessed that part.

Here is a video introduction:

Great work Proto G!

How to Use Low Cost Piezo Discs for Automatic Print Surface Leveling

Njal Brekke developed a high accuracy and very low cost automatic bed leveling solution with piezo discs. You can easily build it yourself for around 20 USD.

He describes his project as:

Auto Bed Leveling using piezo electric discs for very high sensitivity.
Mounted between the bed springs and the z-stage, any force down on the bed can be registered and used as a probe signal. Hence one can measure when the hot-end touches the bed surface. No modification to the hot-end or carriage is therefore needed, and the probe is insensitive to temperature.

This is still a work in progress, so although it is working for me in it's current form, it needs constant tuning as the circuit is not yet perfected, and the mechanical mounts have some known issues. A new circuit and new mounts have been designed but not yet tested.

So far, I've tried to only use parts available from sparkfun. I'm guessing a total cost for all parts of less than $20 USD.

Video of the setup in action:

Hacking IKEA tables into 3d printer enclosure

If you want to get high quality prints you can use a printer enclosure to stabilize the temperature making it a protective isolating chamber. Stable and higher temperature can prevent warping and other heat related damage to your 3d printed object.

Here you can see how to make a simple DIY enclosure from two IKEA "Lack" tables and some acrylic panels. It makes internal temperature stable at around 40 degrees centigrade compared to 20 degrees centigrade of room temperature. It also features extractor fan for fast cooling.

Do remember that you can also make a 3d printer form IKEA furniture:

Two cool DIY 3d printer enclosure projects

Jason Powell has amazing home makerspace setup he made by himself. He has a really BIG enclosure with wide filament holder.

He published his designs for this spool holder at:

I'm soooo jealous Jason!

Michael Teeuw made his enclosure from MDF with some LED stripes and documented his construction process.

How to make a DIY plastic shredding device from wood pieces and metal pipe

dmwatkins developed and published this DIY plastic shredder that you can use to recycle your failed prints or scrap plastic to make new filament as a pre-processor for a filament extruder.

It uses some wood pieces and cut metal pipe and it is hand operated. Rough and basic but gets the job done.

Make a 3d printable copy of your favorite sneakers

iwillspy13 has made an Instructables tutorial on how to make 3d model of your favorite sneakers and 3d printe them in flexible filament. It is not a full copy but a copy of a inside that fits your feet.
Those shoes are probably not usable as the material will probably fall apart when used but it it an interesting project.
We need better materials for DIY shoes :-)
