Xacto knife insert
thingiverse
The insert of my Xacto knife broke (see photo). First I wanted to buy a new holder, then I decided to print a replacement. The model was quickly made in Fusion 360. I printed it with 0.1 mm resolution and in PETG. Although the M5 thread is modelled, after printing I rethread the end. The whole thing came out fine. By using it I found that the insert made with PETG is not as strong as I liked. I will try if I can change the design a bit to make it more robust. In the mean time I published the Fusion 360 file. When you modify it please share your results.
