3D Solutech MasterSpool

UPDATE

V3 updated with a 54mm diameter opening for those of you with non-stock spool holders. This file has not been tested but I expect it to be similar to V2.

VERY IMPORTANT

Be gentile putting the spool together. Further, PLEASE UTILIZE THE LOCKING MECHANISM! There are small holes near the inner circle that are intended for a small piece of filament to go through. This locks your spool together. Without doing this, your spool will be prone to opening up. See photos.

Wasn’t able to find a minimalist 3D Solutech Masterspool that I liked, so I decided to remix one. I hope this helps.

Recommendations (not necessary, but helpful):

Material: PETG

Layer height: .2 to .32

Infill: at least 15%

Infill Pattern: Gyroid

Shells: at least 3

Speed: 60 to 80 mm/s

No Supports Needed

I printed a pair in 5hrs 45 min with 85g of material using PETG with 80mm/s, .32 layer height, 3 shells, 15%infill, and Gyroid pattern. This was a fast draft but turned out well. The whole benefit of printing this model is to reduce cost and print time. Some of the other models will take nearly a day to print both pieces. This, for me, was unacceptable.

Final note, since this was a remix, I took shortcuts in designing and left the interior circle much smaller than a standard spool. It is still large enough to fit on a standard Ender 3 spool holder, and I actually think it turns easier and with less resistance than a normal spool.

Enjoy!
