Measure the kerf of a laser cutter without a caliper!

**Instructions:**
To determine the kerf of your laser cutter:
* Cut this file with the desired material, speed, and power.
* Drop the gauge through one of the holes in the tab.
* When the gauge sticks, read the first label _above_ the tab. This is your kerf.

**How it works:**
The width of the gauge (in the file) is stepped, starting at the width of the hole and increasing 0.004" at a time. The difference between the (physical) width of the hole and the gauge is 4 times the kerf (once for each side of the hole, and once for each side of the gauge). When the gauge fits snugly, the extra width of the gauge exactly compensates for the kerf.

I own an original Space Invaders but I wanted to build one for my daughter.

The sketch-up file contains all the parts. Some for 3D print, some laser cut, and one CNC. It uses a cheap 5.5 inches TV and a Raspberry PI.

The cabinet scale is for 5.5mm MDF.

Ill post some other schematics later.

Derived from thingiverse.com/thing:41823.

Each layer was converted into .STL and into vectors ready for laser cutting. The original thing only had a step file and could not be used easily.

Introducing iMacerslide. I needed to move my iMac to the back of the desk in order to free up some desk space. So I decided to use Makerslide to create my desk stand. Very simple design. Nothing complicated here.

The file "iMac Stand Front" is a cover for the front of the 3/4 inch plywood. I used this part as a way to level the stand. Then I covered it with a piece of angled aluminum and added a brushed finish.

This is a simple test object to find a tight fit when connecting 6mm material.

This is an Air Nozzle for my cheap DC-K40 Laser cutter. Inner diameter is 26mm. I put a 6mm silicone tube on it! The diameter of the connection is 8mm, so that the tube sticks to it very well.

This turns an empty Beer bottle into a pretty candle holder

#V-Slot Linear Actuators
##What are V-Slot Actuators?
######V-Slot linear actuators are modular building blocks for your machine ideas!
####They are made up of OpenBuilds V-Slot Aluminum Extrusion, a Mini-V Gantry System, and 2 End Mounts. This creates a low profile, high speed, belt driven linear actuator.
The V-Slot actuators are unique because the End Mounts contain mounting holes on both the back and bottom that allow connections to the Mini V Gantry Plate as well as V-Slot extrusion.
####V-Slot's linear actuator easily and quickly allows creating mechanical assembly's and motion control systems for just about any type of platform you can imagine!

A very basic jewelry box that can be cut from 1/8 in material

Derived from a box for laser cutter. I wanted a parameteric version for various material sizes. Could be used for any general purpose box

A cutout design for a glass piece that you can put over the heatbed of a Prusa Mendel from Makergear. It has all the holes necessary for the screws plus a cutout to allow the connections and LED.

This is a Toy/Concept

Sketch of a model.
Model files to come.

This is a table top stand for a 7" tablet. You could use it to turn your tablet into a phone frame, video player or book reader. But i designed it to be used as a scoreboard for our home magic the gathering card games,to give them a bit of professionalism. I wrote an android app to go along with it for keeping score called Score Keeper and it's available for free on the google play store also at: play.google.com/store/apps/details?id=net.delaney.mobile

A chicken shaped catapult cut from an A4 piece of 3mm acrylic or plywood. Developed by myself AJ Booker, for my client the Nottingham eLearning Centre nelc.net it is one of 8 FREE projects I designed and developed on the notadesktidy.org website I set up for them. Each includes 3D model files, a user manual, sample files, images, introductory films, worksheets and powerpoint presentations. The catapullet includes an extra presentation where I narrate the steos in designing and prototyping the catapullet

Model furniture to cut out and snap together.

At I Heart Engineering, there have been a few issues in which the TurtleBot 2 was damaged during shipping. The problem is that we currently do not manufacture our own boxes, in fact we still cannot manufacture our own boxes. However, what we can do is come up with our own structural packaging solutions to protect our products working within the constraints of "stock" boxes acquired from elsewhere. The first effort was directed at protecting the Kobuki base of the TurtleBot 2 during shipping. Currently, the shipping department modifies the already existing Kobuki packaging to fit inside of the "stock" box and foam inserts to protect the plates. Our question now, is how to create support for the Kobuki base using our digital manufacturing tools, or if you prefer, the Epilog Helix Laser.

A simple box with a top that disappears inside when opened. Why store your knick-knacks in boring square boxes? This box has nice round corners and box joints that accent its sides.

I purchased a 160mm round kapton heater from Trinity Labs (with a matching 170mm Borosilicate Print Surface) and needed a mounting solution for my Rostock Mini.

This is a print base that uses three M3 screws with knobs (under the rostock-mini base) to make it easy to adjust. It is spring loaded so it can survive minor miscalibration mistakes.

These are some basic trays I worked up to use up some scrap wood pieces I had lying around. You can resize them for any thickness of material.

Crystalux is a light composed of crystal-shaped modules, which can be connected with each other via magnetic joints. A battery provides the electricity, the magnets lead the current through the structure. Each module can be attached in six different angles, which allows a wide range of possible sculptures. When connected, the modules illuminate from whithin.

This is made ​​by using a 3D printer and a laser cutting machine at f.Labo in japan.
The materials are ABS, acrylic3mm, double-sided tape.

A simple dual use tablet stand. Works in landscape and portrait orientation, with shallow and steep angle.

Works best with 10" tablets

Why have a boring perspex box or lego case, when you can have a tardis blue cardboard laser cut case.

In Belgium we have the tradition that with the coming of a new baby we send birth announcement cards to friends and relatives. Those who come to pay us a visit are then given a small present filled with sweets. To cheer up his room I made him a little chair and a plaque with his name on.

The .svg design files are made in Inkscape (the little chair in FreeCAD as well) and all have my son's name on it. So feel free to replace it with the name of your preference, unless you think this is too much of an effort and settle for the same name.

This is a replacement z-axis rotary wheel for focusing a Full Spectrum Hobby Laser.

Thought I'd upload some of my old designs... 1-UP mushroom with robo-legs paper sculpture

We started with Oomlout's Arduino holder and took inspiration from Adafruit's improvements.
The result is a roomy prototyping plate where you can orient the Arduino either way.

If you don't have your own laser cutter we have plates available here: phenoptix.com/products/arduino-prototyping-board-acrylic-plate-and-mounting-hardware

This is a adapter to fit standard exhaust hoses to the Full Spectrum 40W Hobby Laser and the HPC LS3020 Laser Cutter. It might probably fit a few other laser cutters from China as well.

The standard exhaust fans that come with these lasercutters are not all that great. They are inefficient, leaky, have a non-standard hose fitting, and block access to the back laser compartment. This adapter allows you to fit a standard exhaust hose to the laser, which can then be connected to some proper air filtration equipment.

It was created by Alexander Brock in the RaumZeitLabor hackerspace in Mannheim, Germany, for their FS laser cutter.
