※ Please specify your desired color in the message after purchase. ※ We have created ver.2 of both EN and KAKU, with improved slip resistance, a slight redesign, and adjustments to the surface layer marks. 【For Previous Purchasers】 ※ In conjunction with ver.2, those who have purchased previously will receive a special price of 3280 yen ※ Once only.

Please choose your favorite model. ⬜︎ Features A 25mm trackball case for Keyball designed with a 3D printer. The body is designed to be minimal and compact. Usable both flat and tented. The ball can be easily removed with a little force. Designed for right-handed trackballs, but can also be used for left-handed. ※ 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, there is a slight rubbing feel and sound. Three high-precision NMB MinebeaMitsumi bearings (DDL-415X5ZZ) are used. It may feel a bit expensive, but it includes the cost of 3 bearings and 3 screws. 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. Please 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 to print as cleanly as possible, but please consider purchasing only if you understand that layer marks unique to 3D printing may occur. ※ Support material marks may be noticeable on the back 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.
