This is a mod from my Spool Stand v2 :
But baked for the Printrbot Metal Plus (1412).
You'll need 4 standard 608 bearings, nothing else (except maybe sand paper)
The bars are design for specific and general spools :
- the colorfabb 750g spool is for...gess what !
- the 7cm wide taulman is for Taulman nylon spools
- the 7.5cm wide spool for Printrbot Wood spools
- the 9cm is for general standard Reprap spools of 1.75mm filament
- 2 outside shell
- 25% infill
Get 4x 608 bearings and clip them on the spool stand side axes. Use a little bit of force (this is normal if you don't want your bearings to go away).
If you want to change the bars for different spool don't glue them it will work fine. You may need a little bit of sand paper for the tips if your printer is not perfectly calibrated. Otherwise it should be fine
Happy printing !
