The Camaro - Linear Rail Direct Drive Oribiter

The Camaro! The fastest V6 on rails.Why?The aim of The Camaro is to be an extremely rigid and lightweight 3d printed X axis mount that uses minimal screws, heatset inserts, and supports. Unleash the power of your V6 with The Camaro!How?The X axis belt attachment is on the top of the rail closest to the largest mass on the carriage, the extruder stepper. Very little moment force is created because of the width of the belt attachment to the carriage. Next, the V6 hotend is fastened directly to the 12H rail block using 4 35mm screws. This creates the most solid 3d printed mount possible for the V6 hotend, period. What Else?This Camaro actually reduces jams. The lowest part of the hotend cooler has abundant airflow focused on the lower half of the cooling fins closest to the heat source. The fan flows around most parts of the frame, keeping it cool enough to use PLA+ for mounting the hotend.  There is clearance to rotate your heater block to the back of the carriage giving 80% more viewing area. The cooling ducts are far away yet focused close to the base of the nozzle. Will work on Ender 3 and clones such as GeeetechA10, Voxelab Aquila, etc. MGN12H rail Hotends:E3d V6 or clone (You need to bend some fins)E3d Revo 6 (You need to bend some fins)Dragon HF & SF (No modifications should be necessary)ExtrudersOrbiter 1.5Orbiter 2Dual 5015 part fans40mm hotend fanBOM:4x35mm M3screws-holds everything to rail carriage.

I'll get the STEP file up once I get things sorted out a little better. Stay tuned. ##UpdatedV1.8 Major overhaul ##Split the carriage body from the belt clamp.Eliminated need for supports when printing carriage.No additional screws necessaryCompletely new wider belt clampPrints without supportsWider and way strongerEasier to remove and reattachkeeps the belt down in the 2020 channel, level with the stepper. uses shorter beltTotally rebuilt the ducts from the ground upRemoved all in efficiencies from air flow pathEliminated the need to use supports INSIDE the ducts.Version number stamped on partWeight is virtually the same
