One of a kind Makeshift Spool Holder

I needed a spool holder, I didn't have bearings on hands, I have plenty of PTFE tubes…. so I made this.

PTFE provides excellent gliding and durable surfaces. 

Materials:  

1. Four 4mm PTFE  tube (the most common type), each 104.5mm long. 
2. A sharp cutter. 
3. Cutting guide (optional but very useful)

Instructions:

1. Print  a pair of the model. PLA is good enough. I printed them with 0.16mm layer height, 2 walls, 15% infill.
2. Put the prepared PTFE tubes into the slots. Each holder needs two tubes. (See photos) Tips: insert the ends of the tube first, then tackle the middle. It should be a press fit.
3. Done !

Just like TUSH, it can stand on its own. But if you want better stability, you can make your own tray or something. 

It work well on my 20cm size spools. I haven't tested it on other sizes of spools. Pleaes let me know if it work or not for other sizes. Enjoy!
