Screwdriver shelf for pegboard

This is a screwdriver shelf for a pegboard with 9x9mm square holes with center distance of 38 mm.

My first attempt was with two rows alternating placement so it had room for 11 screwdrivers(first photo). This version has just room for 6 and is more stable.

Its made in PLA except the stabilizing thing under the holes witch is made from Ninja Semiflex. After printing that I cut some lines in it to make a star shape so the screwdriver is stable.

My experience when printing with Semiflex is to go slow, very slow. My setting for Semiflex was:
Print speed: 30
Temp: 235
Bed temp: 50 (but I use double sided tape on the bed so I probably could have used zero)
Bottom layer speed: 15
Infill speed: 30 (not really important for this print as there is no infill)
Top/bottom speed: 15
Outer shell speed: 15
Inner shell speed: 20
