3D Print - iPAD Holder for Treadmill

Tired of using tape to glue the iPad to the treadmill, my wife asked me to design and print an iPad holder for her. Here it is! 


This is a multiple weekends project, since the 3D design took me many weeks to complete. Hope you could also get some inspiration from this and design your own.

Smartphone mount for camera tripod [3D Print]

I needed a smartphone mount for my tripod, so I designed this from a sketch using Fusion 360. I know there are relatively cheaper smartphone mounts for tripod out there in the market, but I just can't help to make one myself to learn.

STL file is available here: https://www.thingiverse.com/thing:4309896

In fill: 70% for the middle part and 20% for rest
Nozzle: 0.4 mm
Layer high: 0.2 mm

For people who like to use this STL file, please be aware that not each tripod mount base has the same dimension, so, I highly recommend you to measure the base before 3D print.

Also, for the middle part, please use 70% infill to make the clip part stronger.



After couple of days struggling with Fusion 360, I was able to make the thing!! :)

My draft sketch about the mount design.

For the base, I printed 3-4 times to perfectly match my camera tripod. I think this is due to the precision of my Ender 3 Pro printer or PLA material.
After assembled the 3 parts together

Mount smartphone on the printed mount, perfect!

Place the smartphone mount on the camera tripod

3D Print; Howto remove broken filament

Problem to solve for 3D printer:

Filament was broken inside the Bowden tube during a print.

My printer is Creality Ender 3s (or Ender 3 Pro). Maybe the tension on the filament spool was so tight caused filament broken inside the tube.

How to remove the broken filament:


  1. Turn on Ender 3s 
  2. Adjust nozzle temperature to 210 degree Celsius (keep it at 210 degree the whole time)

    From main menu -> Control -> Temperature -> Set it to 210
  3. Raise the Z axis to see the nozzle from below
  4. Remove the nozzle with a wrench. Remember the nozzle is heated at 210 degree; it's super hot!  It's better to use a socket wrench to remove the nozzle.


  5. Cut the end of filament flat and then push it through Bowden tube, until the broken filament is pushed out of the Bowden tube.
  6. Use the socket wrench to screw the nozzle back to the printer. 
  7. Be sure the nozzle is really tight and level the bed before try to return nozzle back to home.  Here is what happened to my magnetic bed! (see below)  I forgot to level the bed and hit the HOME command, then the nozzle scratched it badly! (The photo shown was after I cut the scratched part off the bed.)
  8. Readjust the bed with paper method
  9. Done.

3D印表機要解決的問題:

在3D列印過程中,線材在送料管中間斷掉了

我的3D印表機是 Creality Ender 3s(或Ender 3 Pro)。 可能是我把線材軸上放在地上, 造成它的張力過,導致線材在送料管內斷裂。

如何取出折斷的線材:

  1. 打開 Ender 3s 電源
  2. 將噴嘴溫度調到210度(一直保持在210度)

    從主選單—>控制—>溫度—>設定為210
  3. 用手旋轉Z軸,從下方看噴嘴
  4. 用扳手慢慢的轉下噴嘴。 注意: 噴嘴已加熱到210度,超級熱! 最好使用套筒扳手轉下噴嘴。


  5. 將新的線材剪平,然後將它推入送料管中,用新的線材推出斷的線材,一直到把斷掉的線材從送料管裡面推出來。
  6. 使用套筒扳手將噴嘴擰回到印表機上。
  7. 請確保將噴嘴確實擰緊並請整印表磁床的水平。
    我在還沒有調整水平時, 就去按下HOME 的指令! 然後噴嘴就嚴重刮傷了我的磁床!
    (照片是我從磁床上割下來劃傷的部分,右邊沒受傷的部份繼續用,哈!
  8. 採用紙張的方式重新調整磁床水平
  9. 大功告成
