Juzam's Cold Soup

These are the printable parts for a filament spindle box.

The housing is build from wooden parts without need for a laser cutter (only rectangular parts, easily available in most hardware stores/home improvement stores).

I wrote down the whole project in detail in my blog post at pleasantsoftware.com/developer/3d/2010/07/29/chipboard-screws-are-the-new-nuts-and-bolts/

Integrated stepper motor with built-in stepper motor driver
UIrobot supply integrated stepping motors with built-in UIM miniature stepper motor driver or stepper motor controller. UIrobot dedicate to achieve electric automation, process automation, electromechanical integration by stepping motors. UIM branded stepper motor driver/controller can fit onto NEMA17, NEMA23, NEMA34 and NEMA42 stepper motors seamlessly by corresponding flange as a built-in control and drive unit. Space saving, cable saving and design time saving integrated stepping motor specialists.

This is the pfiercest printable pfrostruder around!

I wanted to expand my printing capabilities and instead of actually buying a Frostruder, I came to the conclusion I have an awesome 3d printing powerhouse...Why not just print one?!

This is still in the beta test stage, i'm waiting for my solenoids to arrive, but thought I should release this and see what people think and or can come up with to improve the design.

This is a pololu stepper controller carrier. It has connectors to main board via 10pin, 6pin and 0.1" header/screw terminal or 3.5mm screw terminal connections. Endstop connections via 3pin 0.1" header, rj45 or 4pin cdrom-style connector. Motor connections via 0.1" header/screw terminal or 3.5mm screw terminal. Microstepping selection via jumpers for full, half, quarter, eighth and sixteenth steps. Should be a drop in replacement for MBI stepper controller to provide microstepping.

Someone in the lab heard I had a 3D printer and asked me to make a replacement part for a broken PCR machine. The part was a flat black rail that was used as a lid interlock by the machine, to hold the heated lid down on samples during PCR.

Because the part was just screwed down, I measured the dimensions of the lid interlock and the screws for the original part, and threw something together in OpenSCAD (after much procrastination).

It's not as sturdy as the original part, but as anyone who works in a lab will know, the costs of getting anything technical repaired often exceed the price of a new machine. So, I'll just print 20 of these so the machine can have a nice long life!

The machine was, to be precise, a big red Biometra T-gradient machine, which the lab was using to do 96-well plate PCRs. The heated lid was essential for the task or the samples would all evaporate.
