Creality Ender 3 Direct Drive Spool holder (2020 Extrusion) Remix

<p>I really like sapencil's original design, but I encountered two small problems with it. The first one was that the holes for the heads of the bolts were too small, the second was that the walls on the cylinder part were very thin in the zone where they are squished by the “clip” - which forced my printed part to deform.</p><p>This is a very simple remix. In the “spool mount” part I increased the size of the hole by 15% so it should easily fit a stock M5 bolt, which has a pretty large head. In the “spool cylinder” part I roughly doubled the thickness of the walls where the clip goes. I also made the entire part a bit longer (it was signifacntly shorter than the original Ender 3 cylinder - not that it matters, but I thought it might help with some non-standard spool sizes). I also made the rim taller so there's even less of a chance of the spool falling from the mount.</p><p>For the “clip” part and print instructions visit the original design: https://www.prusaprinters.org/pl/prints/32671-creality-ender-3-direct-drive-spool-holder-2020-ex</p>
