Hawke Filament Perch for Snapmaker 2.0
Description
Is your Snapmaker 2.0 Slinging Filament Everywhere While Preparing to Print? Print a Hawke Snapmaker 2.0 Filament Perch for yourself! I was forever frustrated with the basic Snapmaker 2.0 A350 filament mount. The unit stretched so much filament from the spool as it prepared to print that the excess filament would fall off the spool and risk being tangled. I ended up babysitting my printer to hand-wind the filament at the beginning of every print. I created this filament spool perch to solve this problem. The spool is now carried on the horizontal support bar. The action is so light, the filament itself turns it left and right as the head moves back and forth across the horizontal bar, always pointing it toward the print head. I have tested the perch with multiple height and width 1kg and .5kg spools with great success. I also tested its strength with a 10lb dumbell (kids, don't try this at home!) but I am not sure how that much weight would affect the printer's performance. This was my first real drawing in Fusion360 and I am very happy with the results. Both of the parts print straight out of Luban without supports or tinkering. You could even combine them into one print on the bigger printers. I didn't get exact print times because I ran them overnight, but they are >10 hours with PLA at normal quality using the default settings for PLA in Luban. I designed the solution around mechanical parts I already had from a previous project. The exact parts I purchased come and go on Amazon, but similar parts seem to always be available. Here's what you will need: 1 @ 3D printed Perch Mount 1 @ 3D printed Perch Swivel Platform 2 @ 5x100mm axle rods - these are usually for remote controlled car axles. ~$7 for 5 pack https://amazon.com/dp/B01B27MJC6 9 @ 5x11x4mm bearings - these are also for remote controlled cars. ~$9 for 10 pack https://amazon.com/5x11x4mm-Metal-Shielded-Bearings-MR115ZZ/dp/B00XQ9174U 1 @ 5x20 clevis pin, or similar pin ~$9 for 10 pack https://amazon.com/gp/product/B0816NFFS1/ 1 @ optional cotter pin or split ring to secure the clevis pin (I didn't) You will also need four of the M4x10 screws included with your Snapmaker 2.0 if you haven't already repurposed them. To assemble the unit, see photos and these instructions: 1. Use M4x10 screws included with your Snapmaker 2.0 to attach the Perch Mount to the center of the horizontal bar of your printer. 2. Snap 4 of the bearings on the nubs sticking out of the sides of the Perch Swivel Platform. I did this by pressing with my thumbs, but gentle tapping with a tool may be necessary. Using a second bearing as an extender on top of the first may help. 3. Press one bearing into the center hole of the Perch Swivel Platform. 4. Put a bearing at each end of a 100mm rod and snap the combination into the top of each of the "wings" of the Perch Swivel Platform. 5. Put the clevis pin or a similar 5mm pin through the center bearing in the Perch Swivel Platform and lower it onto the Perch Mount, inserting the end into the center hole of the mount. Optional: insert a cotter pin or keychain ring through the hole in the clevis pin to secure it. I left it unsecured. 6. Move and shape the 3D print head's data cable so that it lays fairly flat against the horizontal bar that the print head travels on. It should not interfere with its operation. 7. Stand your filament spool on the two 100mm rods. 8. Feed your filament into the print head, being sure that the filament loops OVER the print head's data cable. 9. Print your first print but watch to make sure the print head's data cable does not interfere with the operation!
