As all thing are subjected to change and a better mouse traps to come along. One has.

It’s been a month since I bout my Thing-O-Matic (TOM). After the first two weeks the belt on my Automatic Build Platform (ABP) was pretty warped from all the stuff I was printing.
So I wanted to be able to place the Heat Build Platform (HBP) on it and save the belts on the ABP. But it was a pain to change them out. The few examples I did find here ether required you to cut into your brand new TOM or buy some new parts. So I made my own setup. The requirement was to stick with the original part that came with TOM and not to slice and dice any of the parts up. (Since you never know when someone else comes along with a better mouse trap}
This is the design I came up with it reuses all of the original part except a second heat platform store.makerbot.com/makerbot-thingomatic-heater-board-v1-1.html . Unless you decide to use the non-heated platform.
I have left the "work in progress" on since I think this can have some more improvements. Like something better then the clamps I used on it.
This should save on the belts on the ABP.
UpDate
If you already put one together and there are no problems with it then there is no need to print them out again.
All I did was clean up the models. I also added a derivative of the roller bearing option for thaws who need or want it.

Someone ell has come up with a better solution you may want to check it out.
Up and working - Thats a verygood solution, i have added small pads of stif foam on the corners of the top plate - removing a 1/2 mm of "slack". Im Working on the ABP fit, but i seems that the APB also have other issues that needs to be resolved....
Thank you for a nice solution. 8-)
Working on it - Now the Platform an carrige is complete. But Congrat - This version is very good :-D - The tightness of the hooks can be adjusted by nudging the hooks on the top plate. I think i will Glue top and gook together.
I will have to wait for my extra Heat PCB to continue, but i can work on the adjuster and the alluminium top plate.

P.S. don't forget to set you z-height for the different platforms.

I have turned the "Is this thing a Work in Progress?" off. So this will be archived just in case someone needs replacement parts.
In a few weeks I should have two new Changeable X carriages, one similar to this one with a mechanical lock down. And a second one with a narrow base to add up to 40mm of movement on the “Xâ€. This will allow you to use a wider platform.

I final got around to tighten up the designs and add the roller bearing option. This shoud finish the design for now.
Untill I work out a better latch system that can be printed. :)
Hi I have printet out the Under parts of this Thing. It seems that the Tap Dimention is
H =4.8 but the Tap Holes are H = 5.8 - Its ok to have some "air" but 1 mm is to big in that respect - the parts are not seating into position.
The same goes for the Thicknes that is 4.1 mm, but the Tap Hole Deth is 4.6 mm.
When Taps and Holes matchup i Will make a 8625 that matches this design, but there might be a problem of freespace bewveen the upper bearing and the Top Plate... 8-)
This one was a bit on the ruff side. I had to learn googe sketch up, how much the plastic shrinks and how to compensate for the spacing.
In the next version I probable remove the center of the top plate and put trapped holes on the side slots. This should give a lot of room for roller bearings option. :)
Just what i was waiting for - Ill look into the http://www.thingiverse.com/thi... integration. ;)
Oh, I like the look of the laser gone plastic. Someone can go either way with this and if you go plastic you can keep the MBI look and feel (nostalgia) while going custom.
You could integrate this: http://www.thingiverse.com/thi...
In fact, I would probably also copy the belt attachment from this: http://www.thingiverse.com/thi...
Overall this is a great idea, I will try it.
Funny you should mention that. The design had the second set of idler holes removed. But I ran across them a day before I posted this. So I added the second idler holes for this options. I don't have a spare set of roller bearings so I can not test and fit this at this time.
If you want and have the roller bearings give it a shot. there maybe some clearings problems with the top plate and clamps. Also look at the belt idle arm it has a notch at the top . This is for the clearings of the bolts from the top plate. :)
this is just easier.
What is that?
a) The ABP comes with a connector nowadays
b) You have to disassemble and later re-assemble, tighten and calibrate it if you do not modify the mechanics.
Why are you using T-slots in printed parts where trapped nuts are possible?
And why limit yourself to flat parts if the tool is a 3d printer and not a limited laser cutter?
I started this with the laser cuts as a template. I could have used other methods but it would have been a few more week before I could posted this. The build dose have a lot of room for improvement but it works. I have it running on my machine. :)
Marcus I really want to like you, you are obviously bright and you make some neat designs. You need to lay off of other people's designs though. You are far too critical of other people's work. It is one thing to hold yourself to high standards, it is another thing entirely to apply those standards to other people without knowing the first thing about those people. He just got a thingomatic last month and he is already posting upgrades to it. I'd say that is pretty cool. Again I like a lot of your designs and you seem like you care about thingiverse as a site (at least about the quality of the things), I just think you may be alienating potential designers.
Any of you guys want to give some feed back on how this worked for you.

Yes - but i have to print it first - maybe in the weekend. 8-)
