About this 3D model

Icarus 2 is a strong, lightweight and dimensionally accurate one-piece carriage for the QIDI X-Max, X-Plus and I-Mate (and I-Mate S) that was designed focusing on strength and ease of maintenance while keeping it very lightweight. Icarus 2 is based on my popular Icarus 1.x mod but with a number of key improvements: A universal carriage for all supported printers, regardless of extruder and hotend. Instead, you print a mount for your chosen extruder and hotend that install with just four screws meaning you can quickly swap to another extruder and hotend while still using the same carriage, improved maintenance. Hotend fan upgraded from 4010 to 4020 - improved cooling performance and lower noise level (4010 fan is still supported with optional printed distances). The belt teeth are now on the belt peg and tensioner instead of the actual carriage. Proper belt tensioner for both open and closed (stock) belts. For the stock belt the tensioner is optional but recommended, you can attach the belt peg alone if you like. Support for the new wider Qidi PCB supplied with some printers. Increased blower fan stability. Supported Extruders Orbiter 1.5 Orbiter 2.0 Sherpa Mini R1 Sherpa Micro R1 LGX Lite BMG Supported Hotends Dragon Dragonfly (both BMO and BMS) Mosquito (and clones) V6 (and other hotends with V6 groove mount) Rapido HF K500 You can use any combination of the above, just print the appropriate mount. Why? I have earlier developed the Hercules mod. While print quality with Hercules is just as good as this, the BMG extruder and the V6 groove mount are not ideal for flexible filaments. This design uses a rigid mount and has a much shorter filament path from the extruder to the hotend. I also wanted to offer a truly lightweight option which this is. What to print Print these files from your extracted zip file: icarus-carriages/icarus-2.1-normal.stl belt-pegs/icarus-belt-peg.stl belt-pegs/icarus-belt-tensioner.stl fan-ducts/icarus-fan-duct-2.5.stl You can also print the optional dial holder if you're going to use one. Also, print the mount for the extruder and hotend you have chosen as well as its corresponding PTFE cutting jig. For example: mounts/mount-sherpa-mini-r1-dragon-2.1.stl ptfe-cutting-jigs/sherpa-mini-r1-dragon-and-mosquito-ptfe-cutting-jig-14.70mm The PTFE cutting jig is for a short piece of PTFE tube used between the extruder and the hotend in the cold zone where it does not deform from heat, it's required to lead the filament to the top of the hotend. Dragon and Mosquito use the same length of PTFE tube which is why they share jig. BOM - Bill of Materials I buy most of my 3D printer parts from quality stores on AliExpress. Shipping takes a while from China but quality is excellent and the prices are good. I might add more stores to the BOM later but it's a lot of work keeping it updated and current so I will try to keep it short. If the links do not work disable your adblocker or use a VPN. 1. Extruder (pick one) All of the supported extruders below are low weight with dual gears and are excellent for flexible filament out of the box (excluding the BMG, not very good for TPU). Use whichever you like and fit your budget. Orbiter 1.5 Extruder (genuine) Orbiter 2.0 Extruder (genuine) Sherpa Mini R1 Extruder (genuine) BMG Extruder 2. Hotend (pick one) I can highly recommend the new Rapido K500 Hotend that in fact was made specifically by Trianglelab for us/Icarus users so thanks to Trianglelab for bringing us this product. It's not cheap but it includes both the thermocouple and the heater so you do not have to buy those separately. It has performed excellently at speeds up to at least 200 mm/s in my testing the past month. Normal Rapido hotend is NOT supported as it uses a thermistor, only the K500 one from the BOM works. Dragon and Dragonfly are also great options. Other hotend options are Mosquito and clones (NF-Crazy for example) but they're not linked from here. Rapido K500 Hotend Select “K500 Rapido HF”. No need to buy a thermocouple / heater cartridge with this, it is built-in! Dragon V2.0 Hotend - Unassembled Parts required: Heatsink - Heatbreak - Heatblock - Screws - Nozzle Buy one of each above and assemble yourself, it's easy. For Heatsink select “Heatsink V2.0” and for Heatbreak select "New Core-SF V2.0" Dragonfly BMO or BMS Hotend Both BMO and BMS is supported by Icarus. V6 Hotend Budget choice, reliable. Select “1.75 mm all-metal”. 3. Thermocouple / Heater cartridge Notice: If you went with the Rapido K500 Hotend above, skip these two purchases. The budget thermocouple is fine, I've used a bunch without issues. Buy a spare. The sensor only is needed. For heater I recommend a 24V 60W heater cartridge, a 50W will also work well. TL T-K500 Thermocouple (3 x 15 mm) Budget Option: T-K500 Thermocouple (3 x 15 mm) 24V 60W Heater Cartridge 4. Hotend fan I like to use Sunon Maglev fans, good quality and not too noisy. If you plan on printing > 350 C a lot you may want to go for the second option (
