Remix of SpeedDrive v1 - Ender 3 direct drive mount by sashalex007. I initially only wanted to make a slight remix in order to use a pancake stepper. The goal was to make it lighter and get back the full length of the X axis (as the original design limits it a bit). Unfortunately the pancake stepper is not strong enough and kept skipping steps, even with increased current. So instead I ordered a 1/3 geared extruder to overcome this. This unfortunately meant a total redesign of the mount, but after a couple of tries I managed to align everything. So far it's printing fine, just the stepper get's a bit hot when printing at 100mm/s. Probably have to fiddle around with the current settings a bit :) Parts used: https://www.amazon.co.uk/Redrex-Assembled-Extruder-Upgrading-Printers/dp/B07L9JJ7XJ/ref=sr_1_1?keywords=Redrex+Assembled+Upgrading+Extruder+kits+with+NEMA+17+Stepper+Motor+for+I3+Mega+3D+Printer&qid=1581533561&sr=8-1 (comes with it's own stepper, but there's also a version without it) 13ncm Nema 17 2-Phase 4-Wire 1.8 Deg Stepper Motor, e.g.: https://www.amazon.co.uk/Usongshine-Titanium-Extruder-Printing-17HS4023/dp/B07L8CGQMB/ref=sr_1_1?crid=22TBO7OLSBKS1&keywords=nema%2B17%2Bpancake&qid=1581534007&sprefix=nema17%2Bpancake%2Caps%2C188&sr=8-1&th=1 Dual fan mount https://www.thingiverse.com/thing:3886952 Hotend cooling duct https://www.thingiverse.com/thing:2612897
