A short video can be found here: ---- Print out all parts. Mount the handle with three 20mm screws and three nuts. The foremost hole remains empty for now. Bead the "clamps" and "brackets" on the 60mm screw and the foremost hole. Install washers on both sides of each "clamp" (see image). Add two nuts on each side of the screw (counternut) or use locking nuts (I used two red plastic gears). Insert the 65mm bolt through the rearmost holes of the "clamps". Let five millimeters jut out on each side for rubber band purposes. Fix the bolt with glue. Use a soldering iron or a side cutter to cut a triangle-shaped flute into the upper part of the syringe's piston (see image). Apply some drops of oil to the rubber seal of the syringe. Attach the front and rear "brackets" and mount the springs. Fix the rubber band that pulls down the "clamps". Clip the barrel (bird perch) onto the syringe.
