The ball can be easily removed with a little force. Designed for right-handed trackballs, but also usable for left-handed users. ※ Please understand that the connection between the bearing mounting hole and the print will be on the front side. Prioritizing smoothness (rotation) makes fine work unstable... Prioritizing fineness (stability) causes stress during large movements... The EN and KAKU created this time are balanced types. ⬜︎ About Bearings Compared to regular ceramic balls, the movement is smoother and improves operability, but on the other hand, a slight rubbing sensation and sound may occur. Three high-precision NMB MinebeaMitsumi bearings (DDL-415X5ZZ) are used. It may seem a bit expensive, but the price includes the bearings and screws x 3. Users only need to prepare a 25mm trackball to use it. ⬜︎ Two Designs EN, with a rounded shape for a soft and slightly cute impression. KAKU, with a solid and angular cool impression. Choose your preference... ⬜︎ Colors (Filament Used) Bambu Lab PLA Matte ・Black…Matte Charcoal (Sales Name) ※ Almost Black ・White…Matte Ivory White (Sales Name) ・Gray…Matte Ash Gray (Sales Name) ⬜︎ Notes Before Purchase ※ We try our best to print cleanly, but please consider purchasing only if you understand that layer marks unique to 3D printing may occur. ※ Support material marks may be noticeable to prevent the print from collapsing. ※ Bearings are already installed, and we will ship items that have been inspected. ※ The main body and trackball are not included. ※ Scheduled to be shipped via Yu-Packet Post. ※ Please refrain from price negotiations.
