A Lift Table! I've always wanted to go full bent and do a lift table model that utilizes bearings. I'm not even entirely sure it needs it, other than that I wanted it. This is one in a series of lift tables, with slightly different configurations. This version utilizes MR128ZZ bearings throughout for the main linkages.
Â
The small version has a base height of 95mm with an extended height of 185mm. The Medium version has a base height of 95mm with an extended height of 275mm!Â
Â
There are two versions. There's a Small version, suitable for the A1 Mini, and the Medium version, suitable for the A1/P1/X1 series. Which version you print will affect the length of M8 screw you'll need to purchase.
Â
[Printing Info]
The central lift assembly utilizes supports you'll want to clean up before you get started with the feet.
Â
There's TPU feet! You can print them in PLA if you don't have any TPU, or leave them off altogether, if you wish.

I use screws from Bambu's Makersupply, and mainly design around those. However, you can purchase self tapping screws from amazon if that's easier for you. I'd recommend an assortment like this Amazon US.)
Â
Important!: This build uses a more diverse selection of hardware, so be aware. The majority of the hardware can be purchased through the MakerSupply. Except for the M8 Bolt and Nuts. Likewise, Most of the hardware can be easily purchased on Amazon, except for the F8-14M Thrust bearing.
30x BT3x8mm Self Tapping Screws (If you don't get the Bambu ones, grab the assortment kit listed above, or something like it, if you don't already have the needed screws)
1x F8-14M Thrust Bearing (You can find these on Amazon and other sources, but Amazon doesn't sell them directly. Would recommend purchasing from Bambu)
1x M8 Hex Cap Machine Screw - (120mm for the Small, like this one from Amazon | 150mm For the Medium, like this one from Amazon)
[Assembly] (The instructions shown here are from the 608 version, with the text adjusted for the MR128 build. The assembly is the same)
We'll start by getting the lift links ready. 4 of the links require minor assembly, attaching the shorter link arms to the mid poinsInsert the bearings in the other links tooFor the handle, we'll use 2 MR128ZZ Bearings, inserted on other side of the wheel. The axle pushes through and is secured with a M3x8mm Self Tapping Screw.We'll attach the back side of the wheel using 3 M3x8mm self tapping screws. We'll also insert the M8 screw through the wheel, and insert a nut onto the other end. The nut fits into the base of the wheel. Tighten down the M8 screw to keep it secure.Now for the main lift mechanism. There's a couple of things we need to do here. Firstly, we'll insert the M8 nut into the one side. On the side with the wheel, we'll put the F8-14M Thrust bearing and then the regular bearing onto the M8 Screw. We'll then insert the whole assembly into the casing. The wheel is ridged to help secure it in place. Under load it should press up against the thrust bearing and rotate smoothly.
From there, we'll use 4 M3x14mm Self Tapping Screws to secure the axles. We'll use 6 M3x8mm screws to clamp the rest of the assembly together. Once assembled, screw the two halves together.Now for the tricky part. We need to assemble the links onto the main lift mechanism. Pay close attention to the way everything is orientated in the illustration.Let's get the base and top ready by inserting the axles partly into the holes.Align the main lift assembly with either the base or top. Push the axles in to secure it in place, and then use M3x8mm self tapping screws to secure everything.Last, but not least, secure the feet in place with M3x8mm screws.
