Where can I find this information?
Just got my kit, can’t wait to get started. First impression, those MR52 bearings are insanely small. I’ve never seen a bearing this tiny before. Just begging for some Micro Machines to be designed around them.

On the bottom of most products pages there are some links at the bottom. But maybe it’s not available on the full kit page and you will have to check the individual product pages. And some files are still missing for some parts

That’s definitely what it is. Nothing on the full kit page, but the individual pages have info. Thanks

I would love to see some weights in the Makers Supply. Especially when doing prints that can’t be too big in size, but need some weight to be stable or have a more premium feel.
Personally I’m a big fan of “tire weights” that are used to balance out car tires for several reasons:
- they’re produced in huge amounts across the world so they’ve one of the best weight / size / price ratio
- they usually exist in only two very common sizes (5g / 10g)
- they’re flat and often have one sticky side so they could easily be inserted into slots or mid print
They should be about 5-8x heavier than 100% PLA of the same volume.

What kit is this? That tiny bearing looks interesting. Do they come in different sizes or only one size?
I think they are referring to the Maker’s Essential Kit A:
@bill.m.davis is right, it’s the Kit A that I have. Those specific bearings are the MR52 bearings and they worked great for a tiny monster truck I made.
Outside of tiny cars, I feel like they would be great for anyone who wants to make finger boards.

How many are there in the kit?
I make a clock with my laser cutter once and I was thinking about trying to design one with my new 3D printer, but it would require hardware like that.
This is kind of exciting to me!
[Edit]
Reviewing the link to item, I think the static load would be to low for a mechanical clock. They require quite a bit of weight/force to combat the gear friction. The larger bearings might work though.

My Kit A came with six different types of bearings. The MR52 are on the far right in the picture and there were six, but I used four on the truck.

These look nice. Bearings, along with springs that this kit also has, are among the things that 3D printers can’t do. I wasn’t planning to start using non-printable parts this year, but maybe I should reconsider.

Don’t mechanical clocks need torsion coil springs and gears, among other parts? I don’t see torsion springs on the BL store.

These will be useful, too, although not for clocks but for something else.
The torsion coil springs that I referred to are like these. I haven’t tried any of these yet. So don’t know if I should recommend MW to stock them. I think even these are too strong for use in the clock that I have in mind.
When I designed the Axe Warrior toy utilizing the escapement mechanism, it took me many iterations just to dial in the 3D-printed coil spring to provide 1 1/2 minutes of run time. I had a blast doing it though.

I have a box full of parts here (Maker’s Essential Kit A) and have no models with which to use any of them. None of the numbers seem to be searchable, none of the part titles are yielding results. I was hoping to have a catalog of options to choose from, but instead I haven’t used a single part yet, and have had the kit for a few weeks now.
Even searching for ‘tiny spring’ models doesn’t really get me anything. Even the bearings seem to be obscure models that don’t really have any example models prepared. I could modify some, but I’d rather just stick to the more common bearings I’ve got in that case.
It would be extremely helpful to start tagging models in a searchable way when they use any of these components.

I would also like torsion springs for wind up toys.

I did already. Also I agree about the need for a part search functionality.

@MakerWorld @Tanklet This would be awesome, some sort of method to search or filter results based on selected Maker Supply hardware components.
Got me thinking about that essential kit. It’s awesome from a designer’s perspective. Lots of toys to play with and potentially use, but from an end users perspective, it’s just a bunch of parts without any instructions.
It’d be nice even on the product page to showcase a selection of models that could be built using that kit with a link saying something like “explore more” that brings up a pre-filtered search that will bring up anything on Makerworld that makes use of the hardware in the essential kit.
On my own personal front, I’m really enjoying the Maker Supply. I don’t really have much, as I couldn’t get the essential kit, but I did have the sample they sent me and some new screws and bearings I ordered. The bearings do seem like odd sizes compared to what I’m use to, but I like the M128 bearings, and I can see using them more extensively moving forward. Probably nothing as awesome as a monster truck though, haha.
I’m mostly going to ditch machine screws moving forward in favor of self-tapping ones, I think, except for where they might make sense. The ones from Bambu changed my perspective, and I’ve got some other ones off of amazon too, and I’m just sold, 100%. Why wasn’t I doing this earlier?!
I’m still hoping they add my favorite magnet size. I saw more sizes, new sizes, but not mine

Yes, will need different sizes and specificaitons. But MW can start with a few that the toy industry commonly use for wind-up toys. The Axe Warrior toy that I designed is a wind-up toy. It would have been easier to design for and have a longer runtime if steel coil torsion spring is used.

Why are parts that contain hardware kits, such as the LiPo charging board and LiPo battery, not available individually? Or are these components no longer available, so that we can no longer use them for construction?
Thx
Hi Kanne, are you referring to our Electric Coffee WDT Tool Kit-K013? Just to make sure which specific kit you are referring to.
