Micro Reverse Compound Crossbow

Really fun for shooting on a magnetic dart plate.
The parts are printed in PLA and PETG at 0.2mm layer height.

Additional Hardware:
2 mm wire (I used a 2mm stainless steel tig welding rod)
magnet D:6mm H:3mm
string (I used a kevlar line from a paraglider)

Post Printing:
cut all the 2mm wire to the desired length
you will need:
- 2x 20mm (for the pullys in the limbs)
- 2x 10mm (for the smaller pullys on the main body)
- 2x 95m (for the sliding cocking mechanism)
make sure all pullys run smoth on the wire. if not, use a 2mm drill to widen the holes a little
press fit the 2 small wirerods into the mainbody (use a hammer or a vise)
press fit the 2 middle wirerods into the limbs with the pullys in the middle
press fit the long wirerods into the cocking sled
put the assemblly into the cocking bracket and make sure the wirerods run smoth i (drill to widen if not)
assemble the cocking handle (press fit)
superglue handle_right and handle_left to their handle bodys
put the trigger and the trigger_roll into the handle_Body_left and close it with the handle_body_right
put the whole assembly through the mainbody (press fit) and make sure the top is planar
Attach the limbs to the mainbody and assemble the bowstring like you see on the pictures. The limbs are really lose, but once the string is tight they will hold.
put the cockingsled assembly in to the guide and pressfit the cockingbracket onto the whole assembly
superglue the boltholder to the cockingbracket
glue the magnet into the magneticbolt

Cock it and have fun ;)
