About
Thingiverse is a place for you to share your digital designs with the
world. We believe that just as computing shifted away from the
mainframe into the personal computer that you use today, digital
fabrication will share the same path. Infact, it is already happening:
laser cutters, cnc machines, 3D printers, and even automated paper
cutters are all getting cheaper by the day. These machines are useful
for a huge variety of things, but you need to supply them with a
digital design in order to get anything useful out of them. We're
hoping that together we can create a community of people who create and
share designs freely, so that all can benefit from them.

Thing-O-Matic/Mk7 Heatsink Upgrade
tl;dr - I upgraded the heatsink on my Mk7...
I was having problems printing with the Safety Orange ABS using my T-o-M/Mk7.
By the time I got the toolhead up to the temperature I needed to extrude reliably on the hot end (225C) the cold end was getting too hot and the feed wheel was chewing into the filament stopping the extrusion half way through a print.
I tried upgrading the fan, and the z-axis but without effect. Plain ABS and Red/Blue both worked but I can extrude them at much lower temperatures.
Luckily I had some left over 2mm copper plate that I used to make the HBP.
So far, so good.
Made a sketch in OpenScad because things have to have a file that isn't an image... Perhaps it will be useful if someone makes this on a cnc.
