if you havent installed the front caster, i would print the new front caster mounts. I would also print the strengthened handle part. The headrest you can keep as is as long as your screw works.
The release notes simply say which bits are Rev B, not why.
I’m still confused as to which parts of the rear / front casters have updated in the Makerworld file. I’ve opened it directly from the site, and I can see the updated handles as “3DTMT XX PUSH HANDLE TOP REV B.STEP” and “3DTMT XX PUSH HANDLE BOTTOM REV B.STEP” and the pin as “3DTMT XX PUSH HANDLE PIN REV B.STEP”.
But for all the caster related ones I have :
”3DTMT K FRONT CASTER MOUNT REV A.STEP”
”3DTMT E2 CASTER MOUNT REAR RIGHT REV A.STEP”
”3DTMT E1 CASTER MOUNT REAR LEFT REV A.STEP”
looks like the makerworld H series one didnt update to B - I am doing that now. I also put the updated Rev B files here - 3D TMT PUBLIC FILES - Google Drive
Take a look at that file. Should be a caster mount front rev B and the rear caster mount Rev A KIT (nothing changes on this except to fit the new mounting plate, so we kept it Rev A)
I understand its a little confusing. The Push handle was ALREADY rev B (we launched that one as REV B) so the new push handle bottom is Rev Bv2
using the shopify built in one.
It’s an extra step, but you can pull the shipping from a Shopify store into Pirateship (exactly what numakers does). I pull my woocommerce orders into it. Pirateship does have better rates on some configurations, like cubic pricing which lends itself to filament shipping. Plus there is the big discount on the UPS+USPS (SurePost - UPS main and USPS last mile).
I just upgraded the shopify plan which should allow for slightly better pricing on it. we’re 1 day into this for kits so gona let it flesh out a bit before making moves.
I did this a few months ago and the price is just a little bit better than pirateship now. So you should be good. Before it was a little bit more than pirateship when I was on the lowest level.
The parts kit is super cheap. I just spent $114 one the parts minus the bearings (already had them) Thanks for putting this together. I’m looking forward to my 2nd build as soon as I finish the 1st.
So we only need to change to revision B on the front Caster mounts if we’re using the kit correct? If we’re using the original Amazon casters the original file should be used?
we’re getting low on them already. i’m finalizing an order for the next 1,000 this evening hopefully. will hopefully be able to keep it under $35 a unit. since these originals were ordered and now pricing has gone up dramatically there. some of my filament quotes were only good for 48 hours.
New front caster mounts are for both Amazon front wheels and kit front wheels
This is huge Scott, thanks for all your work! I just ordered 2 hardware kits….gotta get them before they run out ![]()
It would be nice if we can see some of the parts printed with the Schoolhouse purple gradient and blue gradient. Planning color layout for next TMT.
Only a 4 left currently. i added in the ones I had reserved for me. Rather get them out to people to make for families.
I have 17 of each color kit left as well:

Finalized the order last night for 1,000 kits. Price needs to go up but only slightly assuming shipping costs dont change in the next 3 weeks. Assuming it holds they will be $30 instead of 25.
2 kits are headed to makegood in NOLA for them to do just that. TBH I haven’t even seen this color yet.
Sure does, yesterday the order I placed was was $66 in shipping, and today it’s only $39 for that same order.
Make that 3. I just ordered one ![]()
Ordered one kit of each color so I am ready for the next build.
