TT Motor DC5V 59RPM CCW Single Axis(1PCS) - LA001

Description

This is a 4:1 speed reducer for the Bambu Labs TT Motor LA001. It reduces the RPMs from 59 to about 15. This configuration is for vertical output. The connection point is a square hole 10mm x 10mm x 5 mm. The base can be integrated with any project by importing the STL file.

I would enjoy seeing how you put this to use. Please post a picture in the comments if you can.

All the TT motors I have (and have ever seen) have a shaft that protrudes out both sides. There needs to be a hole for the shaft on the underside to protrude through the base plate. Are there motors that don't have the shaft on both sides, or are you assuming the users will add that hole themselves when they incorporate this into some larger design? If the latter it would still be helpful to have an indentation or mark in the base plate so that we could position a hole ourselves.

@JimLarsen

The TT motor sold in the Bambu store has only one shaft. and I agree it is somewhat unique.

@gtoal

Replying to @JimLarsen :

Makes sense. Well I need to incorporate your excellent gear train into a larger unit anyway so I guess I'll import it into OpenSCAD as an STL and cut a hole where it needs to go. I'm hoping to use this to drive the Pasta Lite filament respooler instead of the manual crank (which is why I need to slow down the RPMs). Or I could just cut off the second shaft from my cheap $1 generic TT motor. I was hoping to avoid making an irreversible change until I was sure I was going to dedicate the motor to this project but I think I'm committed to doing it now so might as well reach for the hacksaw now :-)

@Luis_Felipe

I will post a profile with a hole thank you for letting me know because I was going to print it and would have to drill it with a drill

Excellent gears. I'm going to try to merge your gear train with the mount from https://makerworld.com/en/models/1289074-tt-motor-mount and try to make a motor for https://makerworld.com/en/models/930059-pasta-lite-receiver-a-pastamatic-remix

@gtoal

Turned out I didn't need a reduction gear, the TT motor worked well enough as a direct drive, so that solved the problem of not being allowed to share designs that incorporate your part as a component.

Missing? is it not in the profile?

@JimLarsen

All the gears are in the print profile. Do you need help getting it to print?

@user_1838314980

Replying to @JimLarsen :

New printer, new software, still have a lot to learn. I'm going to try a second time.

Hello friend, I hope you can help me I downloaded the STL and I only have 3 gears and 1 base I'm not sure if another motor gear and the top base of the smallest gear are missing Thank you

@JimLarsen

Three gears and a base is the entire unit. Just like the picture. One of the gears is two gears in one.

@user_885744336

Replying to @JimLarsen :

Greetings Jim, my friend, I didn't use those parts because I needed all the space to accommodate two 18650 batteries and a humidifier to simulate steam I will review the files and update the comment
