Tevo Tarantula No Slop Kit - Replaces stock acrylic parts with better dimensioned printed parts

thingiverse

THIS IS A WORK IN PROGRESS! PRINT AT YOUR OWN RISK (of wasted filament). When I got my Tarantula kit, all of the moving acrylic pieces had misplaces holes for the wheels which didn't allow from acceptable tightness on the rails - even with the eccentrics in their tightest orientation. The center to center dimensions from the fixed wheel holes to the eccentric spacer holes was ~42.5mm (62.5mm in the case of the X motor mount/right Z carriage which moves on a 20x40 extrusion). I redesigned all of these part with the hole spacing reduced to 41.5mm (61.5mm on the right Z carriage) allowing for proper tightness to be achieved. This kit pairs well with carbochip's Y carriage spacer which has the same 41.5mm center to center spacing - which inspired me to create this kit. https://www.thingiverse.com/thing:1678918 <-- carbochip's y carriage I printed mine out of PLA, .2mm layers, 5 perimeters all around, with 20% honeycomb infill and they work fine, although there is a little more flexing than I would like in the Z carriage parts due to belt tension. Maybe print those solid if you have the time and filament.
