Compact Tripod 45cm (Update - TPU feet caps)

This is a tripod. Compact when folded - diameter is 4cm (38mm) and length is 17.5cm, extends to 45cm, manages to hold a smartphone (around 250g) + 1.5kg weight while fully extended (and 3kg+ when not fully extended), though I wouldn't recommend it for anything so heavy

At the moment I haven't came up with good attachments so you would have to find your own like in example you see in the pictures, but you can use "Modeling attachment" STL file to create your custom mounts in Blender or somewhere else if you have ideas
I will surely come up at least with a phone holder attachment, though I may post it as a separate model

Updates: 

• 12.08.2024 - improved attachment legs and clip for better reliability, added new attachment for ¼ inch screw (11 x 5 mm base of the screw) see on pictures
• 24.08.2024 - added (optional) TPU feet caps. Fit like a glove

Print

On the pictures you see parts printed with black Bambu Lab PLA (though almost any PLA will do), 0.4mm nozzle, 0.2mm layer height, with ironing on top surfaces (which is required for best fit) with all parts taking about 110-120 grams. The latches should be long enough to endure long without snapping, so PETG is optional. M3 Screws are also optional but recommended (see Assembly down below)

All parts are pre-oriented and printed without supports (the only potentially challenging part may be the slider lock due to angle of some of the thinner wall parts)

If you decide to use supports however - avoid using supports on all leg parts as removing them from inside while retaining clearance may be nearly impossible

Walls of all rods and tubes don't actually need 100% infill as walls printed in horizontal orientation add maximum strength 

I have printed it on Bambu Lab A1 on default/stock 0.2mm settings so I'm not sure about tolerances and precision of other printers

You will need to print the following parts:

1. Generic attachment 1 pcs.
2. Attachment clip 1 pcs.
3. Center rod 1 pcs.
4. Center rod slider lock 1 pcs.
5. Base 1 pcs. 
6. (Optional*) Hinge pin 1 pcs. (or 20mm M3 bolts + nuts)
7. Leg connector 3 pcs.
8. Leg main 3 pcs.
9. Leg extension middle 3 pcs.
10. Leg extension end 3 pcs.
11. (Optional) TPU foot cap 3 pcs. 

* If you can manage without it

Assembly

Start with legs:

1. Angled end of end extension goes inside middle extension from the side without the latch. When it fully comes out from other end you can pull the latch up and push the end extension in to retract it, though that's optional during assembly
2. Middle extension goes into main leg tube, from the side with a bigger latch and slides down towards and through the smaller latch
3. Leg connector goes into main leg and gets secured with the big latch. 
4. TPU foot cap prints go onto end extension. Leg is assembled

Base:

1. Insert center rod slider lock into the top slot of the base and align with triangular hole - make sure you can see triangle in the hole because if you can't - you have to insert the slider from other end instead. For best useability you want the slider to face bedplate side up
2. Making sure central hole is unobstructed - insert triangular rod from the bottom of the base - move the slider forwards and backwards if you need to. Then you can slide the slider lock in to lock the rod at desired height
3. Attachment clip goes on top of the rod, printbed side of it should be touching top of the base
4. Generic attachment would go on the top of central rod - align inner bump/latch of attachment with holes on the rod, then slide attachment clip up to secure it in place, though warning - it will be difficult to remove (though utility knife you see in the pictures managed to make it much easier) later as the hole is tapered for maximum friction
5. Attach side legs to the base - latches and bedplate pattern should face inside the base, while top of the print outside. Secure with M3 20mm bolts and nuts (recommended), or use hinge pins instead

It may be stiff at first so move parts around and it should work just fine after a few movements
