Einhell GE-CT 36/30 Li Trimmer Spool
Description
This is a spool (for the nylon strand) for the Einhell trimmer GE-CT 36/30 Li from the Power-X-Change family - should also fit for the Agillo trimmer. My spool gave up after ~1 year by being chafed through. I think a new one is way to expensive (~15€) and buying one each year produces too much waste for something that shouldn't fail so soon. There are two version of the spool: 1) the original one and 2) an durability optimized spool, meant for FDM printers. I guess the spool is best printed in Nylon. I've used regular PLA (maybe use PETG to improve thermal conditions) and used a trick to make it way more durable - keep reading! In general this part expects a well calibrated printer! I recommend printing the FDM-optimized version using a few slicer tweaks and 0.2mm layer height. These tweaks expect that your printer allows basic bridging performance for 25mm. If this isn't true for your printer, use regular supports without these tweaks! * use supports to get the bottom part right * add a support blocker for the hole to the top, in the middle of the spool (see design description) * use bridging settings * modify the infill and wall settings of the top 2-3mm to make it more durable: infill: 50%, walls: 5 or infill: 100% The basic idea of the optimized version is that a metal washer gets into contact with soil and stones, not the plastic tip. This way there should be no to little abrasion of plastic, but you might need to exchange the metal washer from time to time. Read the post-processing section for assembly. Enjoy a spool that won't wear for several years!
