About this 3D model

My dad needed to cut some small pills in half, so I designed this device. The photos are of a working prototype, de files are sturdier. I used #10-24 x 1-½ in machine screws I had lying around, I cut it down to get it out of the way. It should be able to hold even the biggest of pills. I printed it with .48mm layers and 100% infill, but your mileage may vary. EDIT: Someone asked my what razor blade I used, I live in Mexico, so your specific model my vary, but this is what I used: https://www.casamyers.com.mx/item/15300390
