3D printed spring compressor Sven's Chimera 250 (1963) Add comments Jul 142022 I have designed a spring compressor that fits the Chimera monoshock and printed it in PETG on my 3D-Printer. I wasn’t sure if it will work but the material proofed to be strong enough and it worked very good. Leave a Reply Cancel replyYou must be logged in to post a comment.
