@Fifi, the dock workerof"Consumables Turntable Stand"Inspired by him, I redesigned a tray for hardware accessories and replaced the original ball bearing tray with a more easily available needle roller bearing
 

A set on Taobao costs 50 yuan, but my set is priced at 12+5+5+1+5=28 yuan. Well, it's probably around 25 yuan. If I replace the stainless steel screws with PLA ones, it could be even cheaper by 5 yuan. As for the bearings, anyone interested can try to replace them with PLA ones, but I don't think it's feasible. The friction of the printing material is still too high. However, you can switch to cheaper ordinary bearings to save even more money.

Note: The needle roller bearings I used are a bit more expensive, but I've provided details of all the accessories and a Taobao link below

The model can be divided into 5 legs and 3 legs, depending on how you install the screws. If you install all the screws, it will have 7 legs.

2: Needle roller bearings [5 yuan/5 pieces]: 6x10x12, with an inner diameter of 6, an outer diameter of 10, and a thickness of 12.https://detail.tmall.com/item.htm?_u=ljah1vn5801&id=768989148236&skuId=5483657366736&spm=a1z09.2.0.0.14ee2e8dNzSUeV

I want to mention this place briefly. Why did I choose a 25mm screw? Because it can hold two things. I was worried that one wouldn't be enough, but later I realized I was overthinking it.
 

3: Drying box [12 yuan]: I actually had a mishap with this once. I bought a drying box with a height of 22 cm at the top and 19.5 cm at the bottom, but when I put half of the items in it, I found it didn't work well anymore.https://item.taobao.com/item.htm?_u=ljah1vn8701&id=727488034358&spm=a1z09.2.0.0.14ee2e8dNzSUeV

4.1: Washer [5 yuan/30 pieces]: M6X12X2. M6 hole, 12mm radius, 2mm thickness
4.2: M6 [3.6/50 pieces]: Flange nuts. Since we're using them in the drying box, we don't use stainless steel ones at all. After all, if the screws rust, the PLA will get completely wethttps://detail.tmall.com/item.htm?_u=ljah1vn0c93&id=737582666070&spm=a1z09.2.0.0.14ee2e8dNzSUeV

5: Consumables box cardboard. Tuozhu's material tray can be used easily, but the paper tray of "Aileke" has holes, so you can only put the tray on the paper tray and turn it.

------- The size of the tray

Bamboo:

Tray size and weight: diameter 200mm, height 67mm, outer diameter of the inner hole 67mm, inner diameter of the inner hole 55mm, tray weight about 250g.

Aileke: Me too! Actually, there are some differences, but they're not significant. The desiccant box can be put in it

It's possible that some students don't like using screws made of metal. Therefore, bearings are definitely indispensable. The core function of the bearing is to fix the shaft. This device is simply a limiter used to secure the bearing in place.

So I'll deal with it later.Stainless steel straight pinPlease post the accessories of the screw in the comment section. The main reason is that the model hadn't been extracted when I was writing the article.
