Lid insert and bit holder for Sestool Fystainer with an attic. Tolerances are tight so keep an eye on how your printer and material will handle shrinkage. I designed these parts to be printed on a Zortrax M200 with Z-Ultrat material and you will likely need to scale slightly to get the fit right. Please let me know if you need adjustments and I will provide updated files! Current Version for Both Files: V2 V1 Initial release V2 Updated tolerances for looser fit
