Mk II: A Rigid spool holder for Dremel 3D40 / 3D45

This replaces my previous spool holder for Dremel: https://www.thingiverse.com/thing:3088371

The Mk II version let's the filament feed from a comfortable angle and with minimum friction. (Previous version had issues with feeding resistance going up when there was less than 20-30% filament left on the spool. Mk II does not have this problem because it feeds directly into the tube.)

Note: If you already printed the old spool holder several parts can be reused: end cap, safety disc and all adapters.

Note II: I am really interested in making things rock solid and secure. If you look at the photo of the AntiSlipNSlide you will find that it holds the whole unit in a fixed position. It will not fall out. It will not spin all over the place. It will stay in position. I am pretty happy with this design if I dare say so myself :-D.

So without further ado, here is the updated story:

I really love my Dremel 3D40. I have printed insane amounts of stuff on it. At one point I decided to find third party filaments. The flashforge finder PLA filament is compatible size wise (fits inside the machine) so I used that for a long period.

Eventually you run out of colours and I wanted to try the Hatchbox filament. For this to work you need some kind of external spool holder. I tried the https://www.thingiverse.com/thing:1653391 with the accompanying arm: https://www.thingiverse.com/thing:2240843

Even though the spool holder looked nice it was tilting outward because the thin plastic inside the Dremel does not support the full weight of a 1 kg Hatchbox spool.

Enter the "Mk II Rigid Spool Holder for Dremel 3D40 / 3D45". The spool holder has a snug fit and can sustain a lot more weight than 1 kg.

If you use another filament that doesn't fit the "Mk II Rigid Spool Holder TM" just print your own! Dimensions should be: Length of the cylinder should be 68-ish mm. Inner diameter is 18,5 mm so that it is i a snug fit on the spool holder. Outer diameter is whatever your filament spool has for inner diameter.

Some notes on printing. I printed everything using low quality (20% infill), but I'd recommend using medium or high to get a better fit. Supports? Yeah maybe. For the arm you'll need it. You'll figure it out, it's not an difficult print.

A note on safety. When you are printing outside of Dremels box, you are also bending the safety regulations. Please take care and try to understand how you can use this thingiverse thing in a safe way.

Other than designing spool holders I occasionally read a book, there is one book that is about me, you can find it here: https://www.amazon.com/dp/B079BT3RG6

Adapter Bonanza!
The spool holder currently supports the following brands: (Outside diameter for adapter should fit the inner diameter of the filament spool)

Hatchbox (Adapter diameter: 54,5 mm)
Classe (Adapter diameter: 52,5 mm)
3dPrima ( Adapter diameter: 53 mm)
Amazon Basic Pla (Use etiher Hatchbox or Classe adapter, I have not tested this myself)'
Geetech (Adapter diameter: 57,5 mm)
Solutech (Adapter diameter: 57,1 mm)
Dream Maker (Adapter diameter: 51 mm)
Generic (Adapter diameter: 50 mm)
Sunlu (Adapter diameter: 72 mm)

I have had best results with medium and high print quality setting for the adapters.

...drop me a line if you see a need for another adapter and I'll upload it.

Also, one more time: I like to print stuff fast and with low quality setting this may occasionally cause parts to 'almost fit' and you have to use considerable force or a sandpaper. If you have the time I recommend medium or high quality.
