Monoprice Maker Select V2 Spool Holder Extender

thingiverse

Here's another Monoprice Maker Select V2 spool extender! I couldn't find one that met my needs when I wanted it, but I guess I didn't use the right keywords because now I see a few. Oh well. This can accommodate a spool up to 93 mm wide, which was perfect for the 1 kg spool of "BuMat" PLA filament I had (92 mm wide). It only works with spools that have a lot of clearance inside, though... **see note below.** This one is nice because it just extends the original holder, so it doesn't use as much plastic as an all-new holder, and you don't have to worry about any quality issues with printing screw threads. One small downside is that you'll have to drill a hole through your Monoprice holder. **NOTE!** Since this leaves the flange at the end of the existing holder intact, you need a spool with enough room inside to clear this flange. Put one side of your spool on the existing holder and support the other end so that the spool is level... if the spool won't turn freely because that flange is interfering, then this isn't the extender for you! It works perfectly with my ~3 year old BuMat 92mm 1 kg spool, but they may have changed spool designs.
