Longer AM8 SnapIT Spool Holder

Two versions available (both modified in tinkercad):

1. Mod - Same length as original, but removed small feature (circle/shield where rod is sitting) that needed support for printing, now bridging will be enough to print it out.

2. Long - Longer version to accommodate for extruder under the spool
(with this extruder mount https://www.thingiverse.com/thing:2838934)

Only one side available, for other one simply mirror the model.

Thanks for original design, very nice and useful :)
