These are 3-D printed by me using white PLA+ and were designed by jordi_id7.
Each of them holds 40 switches, including springs and tops.
B-Stock lube stations are from my first few runs of the 3-d printer, and have lower print quality than standard. This means that some holes won't fit your switches perfectly, hence the heavy discount.
Full Disclosure: A-Stock lube stations are guaranteed to have switches fit in every slot. However, my 3-d printer is not perfectly calibrated. This means that there will be some cosmetic imperfections in A-stock lube stations that do not affect functionality. Please keep this in mind as returns are not accepted.
