Description

I want a MakerBot, and I've got a ShopBot (that we've done a lot with - becausewecan.org). So I took the Makerbot laser-cut chassis file, and tried to make it into something a CNC router can cut out.

This is a first pass at this, I haven't gotten to cutting it just yet as two or three parts are looking rather fragile and I need to look at some build pics to see if that's going to be a problem or not!

If you beat me to cutting one out (which is likely!) then I'd love to hear how it goes.

how thick is a standard sheet of plywood

With great size, comes ridiculous print times. I was totally going to build one in to the shell of a disused dryer, until I thought about that for a while.

Whoa! I can never get 1/16" bits to do much other than break on me. Seems like they break if you just look at them wrong.

I'm thinking that I might just redesign it a little to use a different joint before I cut mine out.

Instructions

The file is setup to be cut out entirely with a 1/8" bit. Once I get a 'final' that I know works, I'll post up a nested and non-nested file for cutting.

It looks like from simple nesting that the Makerbot takes up about a third of a sheet of standard plywood. You might be able to get four out of a single sheet, and it looks like it might take a half hour at most to cut out per chassis.

I dare you Ben Heck...

Interesting... You could easily scale this up to flat-pack shed/icebox dimensions cut from large sheets of plywood.

well... kinda. Scaling up the chassis is one thing, scaling up the motors
&
amp; hardware is quite another. Once you got up to a huge size you'd start running into issues of things not being stiff enough, threaded rods whipping, etc.

If we wanted a huge Makerbot, we'd just hook an extruder to our CNC-gantry! :D
