Filler spool holder, slim guide

I use Amaz3d spools which have a 32.3mm inner diameter. The guide HugoHuge included was too wide for these. In Tinkercad I simply sliced the bottom off and rounded the edges a bit. Even then it took a bit of sanding but now works fine. Likely less strong than the original, either way it works for me. The only file i've included here is the slim guide, you will still need to download the rest from the original item.

Edit: after using my design for awhile the weakness added by removing the amount I did has become apparent, I've since switched to using https://www.thingiverse.com/thing:3176839
