Spool adapter for 250g spools, easily adjustable

Spool adapter for 250 gram spools with easy adjustment depending on spool width or inner diameter / core diameter of the spool!! 

Adapter should fit almost any spool, it can be adjusted very easily without CAD!! See descriptions below…!

Standard print profiles: “Spool Adapter ASA” and "Spool Adapter PETG":

Since I couldn't find a suitable spool adapter for my 250 gram spools (250 gram spools from 3D Jake (PLA) and spools from RECREUS (TPU spools: for drying in the AMS HT)), I designed this one. 

This one fits my 250 gram spools from 3D JAKE and RECREUS which have an inner diameter (spool core) of approx 52 mm to 53 mm, are approx 42 mm to 43 mm wide, and have an outer diameter of 139 mm to 142 mm.

The spool adapter fits my AMS 2 PRO and also my AMS HT and since I also use the adapter for the AMS HT, I printed a version in PETG and also a version in ASA.

The print profiles are executed with a modifier, so only the threaded area has a higher wall count, which saves filament during printing but still makes the spool very stable.

The external thread of body 1 is 40 mm long and sinks approximately 16 mm into body 2; when screwed together, the spool then has a width of approximately 67 mm with my aforementioned spools.

Print Profile: “Body 2 with continuous thread”

With this print profile, the thread of body 2 is continuous, allowing the external thread of body 1 to be screwed through body 2 so that the spool adapter also fits spools with a different spool width or inner diameter / core diameter.

Please ensure that the protruding thread, in the case of very narrow spools, does not get caught or rub in the AMS!!

Print Profile: "Body 1 thread length adjustable"

Adjusting Body 1 for spools with different spool widths or inner diameters / core diameters:

Since my design has a relatively long thread compared to other designs, the thread length can be very easily adjusted so that the spool adapter also fits spools with a different spool width or a different inner diameter/core diameter. 

For this, I have added the print profile “Spool Adapter Thread Length 33 mm”. This includes a “negative part” through which the length of the thread of body 1 is shortened to 33 mm. If you open this 3mf in the slicer, the Z-position of the "negative part" can be very easily changed using the “Move” function, which allows the thread to be made longer and shorter and thus also adapted for other 250 gram spools. 

Simply click the “negative part” in the slicer, then click “Move” in the top selection bar, and then slide the “negative part” up or down with the blue arrow, OR in the “Position” row, in the “Z” column, increase or reduce the current value of 73 mm by the corresponding millimeters.

If the value of 73 mm is reduced to 70 mm, the thread length is reduced from 33 mm to 30 mm, thus fitting narrower spools or spools with a larger inner diameter. This way, the spool can be very easily adapted to your own spools.

I wish you a lot of fun printing and hope that this print is as helpful for other people as it is for me.
