Modular Modular Synth Table

I designed and built a small table and set of accessories to hold my synthesizer modules and manage their cables.

I ❤ MY PRUSA i3

I bought a Prusa i3 MK3S last October. Prusa has since updated their current model to the MK3S+, but the differences are small. 

My 3D printer is now my favorite go-to tool. I used to dismiss 3D printers as only being capable of making Happy Meal toys. Now I make all kinds of parts for all kinds of problems and uses -- plumbing, photography, telescopes, household appliances. I mostly design the parts in Fusion 360 then export the parts in SLA format to the Prusa Slicer application to prepare them for printing.

Changes to Fusion 360's Personal Use License

In September 2020 Autodesk announced some changes to their Fusion 360 license for Personal Use that may have some makers confused or disappointed.

Autodesk posted details about these changes on their blog: Changes to Fusion 360 for Personal Use

I teach several classes at Chimera Arts Makerspace in Fusion 360. The introductory class in the series: "Introduction to Fusion 360 for Makers" helps makers evaluate whether Fusion 360 is a good choice for their projects and a safe investment of their time.

My initial reaction to Autodesk’s changes is that the move is unsettling and confusing, but, on closer examination of the details of the changes, it may be for the best in clarifying the uses of the software, something many beginners stumble over when trying to come to terms with the huge feature set of the program.

My Shaper Origin Meta Project - Using Shaper Origin to make a worktable to work with the Shaper Origin

I spent the afternoon cutting a multi-function table with a new tool at the Chimera Arts Makerspace: a Shaper Origin handheld CNC router. (New to me at least.)

Completed Multi-Function-Mini table sits on sawhorses and has a rigid aluminum T-slot frame. The front work table is 24" deep and the back extension table can be raised to create a coplanar surface with a field of Shaper Origin tape.

Fusion 360 Classes

I am teaching classes in Fusion 360 at Chimera Arts and Makerspace in Sebastopol.

There is a sequence of two classes -- one is for beginners and the second is intermediate-level.

The beginner class is Introduction to Fusion 360 for Makers; it is a 2 hour class taught on the first Wednesday of the month at 7pm.

The intermediate-level class is Fusion 360 Techniques for Laser Cutting and CNC Routing. This class assumes you have mastered the material from the beginner class and goes on to explore specific techniques suited to working with sheet materials for making multi-dimensional projects. This Fusion 360 Techniques class is taught on the third Wednesday of the month at 7pm.

Each class is $50 and open to the general public. Sign up for specific classes through www.chimeraarts.org.

Book review -- Design for CNC

Design for CNC was written by the AtFAB group who have put together a wonderful collection of open-source [CC BY-NC-SA 3.0] furniture designs.

The book's website will give you some idea of the content.

A box of eggs

Tapered Joints

Some experiments with angled joints.

Alternative Joints

corner snap-fit tenon pieces wrap the circumference of this box

These boxes are experiments with alternatives to the ubiquitous laser-cut box joints.

Postcard Box

This box was created to hold information postcards on an outdoor sign. It is designed to keep the contents dry in the rain. It is made from acrylic and features a reinforced hinge.

Railroad Clock

This railroad platform-style clock was made of parts from a clock that had broken. The clock mechanism, the printed face with the numerals and the bezel glass were reused in this design.

3Dconnexion SpaceMouse Wireless Kit

I acquired a 3Dconnexion SpaceMouse Wireless Kit. The kit bundles a SpaceMouse Wireless and a CadMouse Wireless.

SpaceMouse Wireless (upper-left), CadMouse Wireless (upper-right)

Update: I can no longer recommend the CadMouse Wireless or SpaceMouse on Mac. I have found the drivers have become too problematic. 
I am now using a Logitech MX Master 3 for Mac in conjunction with the Logi Options+ software for my Fusion 360 work. 

Draft Box with Double-Hinged Lid

This box design used Direct Modeling techniques in Fusion 360 and two drop-in hinge widget components which I had previously designed. The links to the original hinge components were broken, and the hinges were then customized for the application. 

Small Tansu

The small tansu was inspired by a mizuya-style kitchen tansu (see below). Fusion 360 was used to design the model at 1/5th the scale of the original tansu. The tansu model was designed for and constructed with laser cutting techniques. There are 187 parts in the assembly - 22 independently moving parts.

Ultimately, this small tansu is intended to be a desktop secretary.

The Voccell DLS Laser Cutter

The Voccell DLS 50 Laser Cutter

In December 2016, after 14 months of delays I canceled my Glowforge order and ordered a Voccell DLS 50W laser cutter. I received my DLS 5 months later in May 2017. The Voccell DLS 50 was $3500 at the time including the water chiller and shipping. Today Voccell lists the price at $5000.

The Glowforge

Glowforge describes their product as a "3D laser printer," but it is the same class of device as what the rest of the world refers to as a CO2 laser cutter and engraver. The Glowforge originally went on sale as a pseudo-crowdsourced project by soliciting pre-orders in Sept. and Oct. of 2015 with an "expected delivery" by Dec 2015. They received $28M in fully-paid pre-orders during the phase.

Many delays and feature-changes ensued, and the first finished units were not shipped until July 2017. Most of the backlog was fulfilled over the following year, but some international orders still lingered.

The Makita Cordless Track Saw

Makita XPS01 saw on Festool MFT/3 table with Mafell dust bag attached.
Note tape over arbor hole to improve dust control.

I love track saws. A track saw is a safer alternative to a table saw for many woodworking and carpentry uses. A track saw doesn't require the dedicated shop space of a table saw. And given a long enough guide rail, track saws are ideally suited to working with large sheets of plywood, acrylic -- the primary laser cutting materials. Many laserable materials are sold in large sheets that are much more economical than pre-cut "project" pieces. And some materials are only available in 4'x8' sheets. So being able to work with sheet goods will increase your range of available materials.

Festool makes excellent track saws that dominate the market for good reason. I've used a Festool track saw for years, and I'm a huge fan. But Makita has turned my head with their new cordless track saw -- the XPS01.

IMPROVED: Fume Coffin Pre-Filter

I developed and built the Fume Coffin - Laser Cutter Exhaust Vent Filter to assist with filtering the exhaust vented from my 50 Watt CO2 laser cutter.

But it's not easy to service the Pre-Filter.

In the original Fume Coffin design the Pre-Filter lines the interior of the cylindrical HEPA filter. And accessing it requires opening the Fume Coffin and disassembling the HEPA filter assembly.

This project replaces (or supplements) the original Fume Coffin's Pre-Filter with an inline Pre-Filter that's designed to be easily monitored (it's see-through) and easily serviced.

This new Instructable is an optional add-on for the Fume Coffin project.

Fume Coffin Instructable - Laser Cutter Exhaust Filter

So I designed and built this.

It's called the Fume Coffin, and it's a laser cutter exhaust ventilation filter for my 50W CO2 laser cutter.
