Reinforcement brackets for Creality CR-10 / CR-10S / Mini

thingiverse

I had been thinking about doing Z-axis reinforcements for my Creality CR-10S printer for a while, but I couldn't find anything that would work for my hotend group. The problem was the height, which I could have missed because the changes made have greatly increased its size (MicroSwiss, BLTouch, fangs). So I designed the whole thing with Autodesk Fusion 360 in order to still have the maximum travel on the Z axis available on the machine and with the fewest possible number of pieces. The material I used for printing is Sunlu PET-G. I love this material! I printed it at 240 ° C with a bed at 60 ° C and a 50% fan. However, these brackets can also be made with PLA or ABS. All you need is described below: Filament (of course!), 2 threaded bars diameter 8 mm and 690 mm in length (on the market you can find them from 1 meter and then equip yourself with a hacksaw to cut them), 8 M8 nuts and 8 washers, 4 M5 Allen screws 60 mm long (with the head) to replace those already installed on the machine, and 2x605 mm of flexible tube 10x1 RILSAN PA11 DIN 73378/74324 PHL of the color you like best to coat the threaded rods (optional). That's all! For the two upper brackets make sure you have a correct STEP/MM ratio. The dovetail joints must be very precise if you want them to stay still. If you find it hard to get into the throat, don't be afraid! With a small file or a cutter (careful not to cut yourself!), you can correct any smudging. Some may say that these brackets are cumbersome, especially in front, but I did so because in this way they go to protect the entire bed when the Y axis is at its maximum excursion. In addition, they leave me plenty of space to be able to conveniently remove my prints. If you like it and build it, thank you for your photos and your comments.
