printing a missing film reel

 i bought an Arkay 16mm developing tank on ebay and neglected to notice one of the reels was missing. it turned out to be quite easy to make a duplicate, even with the grooved indentations on the surface. printed in white pla. ill probably do one in abs, not sure pla would stand up to the develping chemistry very well.

3d Printing Workshop Links

Here is an info page for people attending the 3d Printing workshop I’m giving at Neutral Ground Contemporary Arts Centre in Regina, Saskatchewan.

3d printing links

Makerbot makes some of the friendliest printers around. Makerbot no longer makes kits and now sells prebuilt printers that are ready to print out of the box (fingers crossed). I have one of the oldest Makerbot printers, the Replicator 1.

Thingiverse is the largest site for sharing 3d printed models. All of the models will be available in the .STL format common to all printer software. You can upload your own models to share with others.

A magazine style annual rating various brands. There are way too many brands of printers to keep track of and they change all the time.

A kit manufacturer, the only one I can really comment on because I bought one of these. This is how to get into 3d printing if you have lots of time and not so much money. This kit is based on the Prusa I3 design.

Rhino3d is the CAD software I personally use because I am familiar with it and it works great for 2d and 3d designs. It is a true CAD application for dimensional industrial design, rather than for animation or print designs.

installing new build plate on rep 1

this is me installing a new heated build plate and aluminum arms upgrade for my replicator. this $400 upgrade will hopefully make the whole thing more level and allow me to use both extruders at once. previously my platform was minutely warped and it would not let me dual printed accurately…


Casio patch bays

Here are some 3d printed patchbays I made for my modded CASIO SK1 synths. Each plug is a banana jack (you can get 100 of these on ebay for like 12 bucks) and is connected to a pin on the memory chip bus of the main PCB. To understand how to wire one of these up look at the page at CasperElectronics. The point of the patch bay is to connect these together in a myriad of different ways to create unexpected sounds. Basically I think it makes interruptions in how the encoded instrument sample data is sent from rom chip to processor. Skip to the end of this post to hear a sample.


I made lots of design changes to this simple board and printed it out multiple times to get things nice. I still think the font I chose for the letters is a little unsuitable for this resolution of printer.

In order to mount the patch bay into the CASIO you have to remove the speaker grill. I used a dremel with a cut off blade and finished it up with a hacksaw blade.

To hear what it sounds like, listen to some noisy experiments… this is done with a Korg monotribe with the CASIO Sk1 plugged into the audio input.
