adjustable linear tube guide plus camera holder

Thanks for reaching out!

Here we have a rule not to use a single Ai image. This means every image you see in posts or descriptions are real photos.

Another rule is not to upload designs that are not tested by us  first. So what you see is what you will print indeed.

Hope you like our work and maybe support us. Remember that you can support us for free just by like, follow, share and boost our work.

UPDATE 30-06-2025:

I added a profile that includes an unstuck tool key too help you unstuck the guide from the tube without risking to brake the threads of the wheel… so follow new assembly directions….

One of my best designs so far!

I upload all the stl files also.

demo:

https://www.youtube.com/shorts/GPvotVMgSj0

this is a very unique designed and used fussion to make it true.

An adjustable bracket for general purpose use.

my current project is for mounting a usb microscope camera.

i want to inspect pcb most.

Other attachments to fit on the bracket will be designed in the future for sure.

i wanted to designed something that would be universal for my project so…

trying to keep the limits of a1 mini.

I include 3 profiles.

100mm travel profile has the accessories also

150mm travel profile only

accessories only

The whole linear unit mechanism is printed in place without supports. Just print and use it.

Every revolution of the wheel will move 3mm the bracket.

one more profile includes the accessories I will use for the microscope camera project.

I upload all the accessories on .step files in case someone want to design their own accessory for the units.

• a wheel

I made the wheel with holes so to turn it with my fingers. 

The wheel is attached on the unit with m12 thread.

• a microscope camera holder for the bracket

  To install the bracket on the camera just slide it from the bottom until you here the click!

   

   

  

   

• a base for the linear unit.

The base I upload is designed with a snug fit to the tube so not to use even glue but you can do it if you wish so.

there are 4 holes at the bottom of the base so to mount it on a plate.

I will use a wooden plate for my project so to be more weight steady.

• nut and bolt to mount  the camera holder

This is 8mm thread. If you wish use real life bolt and nut M8.

ASSEMBLY INSTRUCTIONS.

Its really ease to get it work since the whole mechanism is already print in place.

First use the unstuck tool key and screw it on the top until is well tight.

In that point continue to screw until you here the click means that the guide is unlocked and moving up already.

TIP: If you feel that you put a lot of force help it by moving the bracket a little bit left - right.

unscrew the tool key and screw the wheel on top until its tight enough.

Move the guide  far enough so to mount the unit in the base.

If you wish extra lengths, mods or accessories just ask me if i can do it.

for now there are 2 travel lengths. But i will upload bigger volumes if needed by the community…
