Materials: PETG or PETG+PLA; optional FLEX(TPU) for the feet

Supports: Not required

Print settings: 30% infill; 0.25 layer height; Printed on Original Prusa Mini

Hardware:

- 1x M8x160mm hex bolt (spool axis inner bolt)

- 5x M8 hex nuts (1x for spool axis fastening, 4x аs horizontal move limiters of printed spool bolt/nut; 2x nuts tightened up against each other in different directions)

- 2x 8mm x 160mm metal rod/pipe (for vertical spool holder arm)

- 2x 8mm x 200mm metal rod/pipe (for spool holder legs)

- (optional) 2x 608 bearings (for printed bolt/nut)

- (optional) 2x M4x25 or longer (for reinforcement of metal rods fastening)

- (optional) 6x M4x12 or longer (for reinforcement of metal rods fastening)

- (optional) 8x M4 nuts (optional, for reinforcement of metal rods fastening)

Printing/Assembly:

- Print "Spool_Axis_Bolt" and "Spool_Axis_Nut" parts. The material is not so important here, PLA or PETG will be fine.

- Alternatively, if you want to use bigger spools, other variants of spool axis bolt/nut can be used from the original model https://www.thingiverse.com/thing:1241566 . Take a note that in case of bigger spool axis bolt you need longer spool axis M8 bolt too.

- (Optional) Push in two 608 bearings to the "Spool_Axis_Bolt" part

- Print "Top_Joint", "Stand_Base" and 2x "Leg" parts. Recommended material is PETG. This part will withstand a lot of force from the weight of the filament spool.

- Use 200mm metal rods to connect "Stand_Base" and two "Leg" parts. If available, use M4 bolts and nuts to fasten rods to the parts. NOTE: Rods will fit tightly with the stock clearances, a little bit of gentle hammering may be required

- (Optional) Print 4x "Foot" parts with flexible filament (100% infill) and glue them to the outlined areas of "Stand_Base" and "Leg" parts. (CA glue should be fine)

- Connect "Stand_Base" and "Top_Joint" parts with the two 160mm rods. If available, use M4 bolts and nuts to fasten rods to the parts. (longer bolts needed to fasten rods to the "Stand_Base" part). NOTE: Rods will fit tightly with the stock clearances, a little bit of gentle hammering may be required

- Fit M8x160mm bolt to the "Top_Joint" part and fasten it from the other side with M8 Nut

- Use 2 nuts to create first limiter on the M8 spool axis bolt

- Fit "Spool_Axis_Bolt" part on the M8 spool axis bolt

- Use 2 nuts to create second limiter on the M8 spool axis bolt, so that "Spool_Axis_Bolt" part will be fixed on the axis. Using M8 nut limiters you can adjust how easy will spool rotate

- You are done, put your spool on the "Spool_Axis_Bolt" and fasten it with "Spool_Axis_Nut" part
