After me son be diagnosed as a type I diabetic (on April 1st, no less), ya bilge rat, We decided t' upscale an insulin syringe, shiver me timbers, arrr, as comic relief from the new daily routine of carb counting, shiver me timbers, finger poking, blood glucose monitorin' and injections. Arrr!  

T' syringe is a 625% upscale o' a BD Ultrafine 3/10 CC.  It is made from a 1 1/4" polycarbonate T-20 fluorescent tube slip cover for t' main body tube. Aye aye! T' 1/8" acrylic fins are t' shape o' t' finger pads o' t' original syringe.  T' plunger is made from BT-20 with foamcore centerin' rings and 18mm engine mount. T' cap is balsa, me hearties, matey, turned and strips glued on t' make t' ribs. Arrr!  

Recovery is an 18" mylar chute, with a semi-pop pod/plunger design.  T' ejection pops t' plunger back to deploy t' chute, and ejection ventin' pops t' (kevlar tethered) cap off the needle.  T' plunger is stopped 1/2 way back by two cotterpins, me bucko, catchin' a centerin' ring. Avast, me proud beauty! Begad!

It has flown, on a C6-3. Ahoy! It is heavy, so altitude be limited to about 100 ft. T' pop plunger recovery worked so-so. T' chute deployed, matey, but the plunger popped past t' stop, It eventually came free and separated about 2/3 t' way down. Broke a fin and cracked t' cap on landing. Avast, me proud beauty! Begad! We will be making more solid centerin' rings o' masonite and go again. Aye aye! It worked well enough to prove it works, shiver me timbers, just needs beefier CRs. Avast!
