Holds 3@ arrows of diameter ~3.5-5.5mm (freecad file provided if your arrows are a different size). This is not really a remix, but an accessory for the Mini Compound Bow designed by DonStick3l... Don thanks for the wonderful design!:

It is secured to the bow riser with the bolts that hold the string guide part. If your existing bolts are >=2mm 'too long' they will work; otherwise you'll need some longer bolts. The lower non-counter bored holes are just there for clearance in case your arrow guide bolts are too long (like mine).
I printed mine in PETG and it has a solid grip on my 5-5.5m skewer arrows. Not sure if PLA is too stiff or not. Someone please post a comment if you print it in PLA (or other materials besides PETG) and it works well.
Update: 5-18-2018
Anisotropy bit me today. A pair of my arrow clips broke when I inserted an arrow. So I reprinted rotated 90* to take advantage of material orientation. Now it is much tougher to break; actually I couldn't break it during my 'abuse testing'. Unfortunately rotating it means supports are now required; regardless, the end result in clear PETG is actually better looking with the updated orientation. I uploaded a version 2 stl file with the updated correct orientation.

Notes:
I designed the clip walls 1.35mm thick to work with a 0.45mm wall width (0.4mm nozzle). The print takes ~25min with my recommended settings.
Update 5-18-2018:The revised vertical orientation requires supports everywhere (in Cura) to print correctly. Use a support roof for the cleanest print. The print (at 0.2mm, 400mm/s) now takes about 45min to complete.
