Butterfly pen - Balisong Bic - Butterfly knife Bic

cults3d

Butterfly knife (balisong) having no blade but a pen instead . There are 3 different models in the folder: V1, V2 and V mini For the 3, no screw or nut is necessary, it avoids that they loosen. The assembly is planned by interlocking and either by gluing or by sliding filament ends in the holes provided for this purpose . The handles have been cut in 2 parts to remove the printing supports and improve the overall appearance. Otherwise, the V1 (above on the first picture ) was mainly to validate the principle of replacing a blade by a pen and the assembly by filament The V2 is a test to test more spaced handles, otherwise it is also more rounded than the V1, with rivets integral to the handles, the location for the filaments are 2x less and the games have been reduced. The mini version ( below on the first picture ) is more convenient to write but requires to cut a pen . To cut this pen, I took a disc and a 5.5 diameter drill to deburr the inside, you should not be too brusque on this step at the risk of splitting the pen. No worries about ink leaking when cutting the lead edit 11/05/20 : added the mini version and a pen holder d. 5 on the V1 edit 12/05/20 : added V2 , added f3d for V1 and V2
