Filament Spools

My version of filament spools, with filament hooks (on photos there are older versions :-) without filamant hook) there is 4 version that have different thickness (inside): 10,20,30,50mm . They are designed for 1,75mm filament (and the filament holding element).
STL is half of spool so you need to print each one twice.

For assembling you can use wood screw 3mm/3,5mm dia, and 10-20mm long.

**Dimensions:**
*Common for all:*
- External spool diameter: 200mm
- Internal spool diameter: 80mm
- Spool hole diameter: 48mm

**Spool thickness:**
- 10mm inside (16mm total/outside)
- 20mm inside (28mm total/outside)
- 30mm inside (38mm total/outside)
- 50mm inside (60mm total/outside)

Printed on Ender-3 (v1) & Cura, **resolution** 0.2mm, **supports**: enabled, touching buildplate (for filament hooks).
I used some leftovers of filamant to print those :-) , print time around 5-7h per half spool.
