TQFP adapter case

thingiverse

The purpose of the case is to reduce accidental shorts, protection for the pins and an easy way for mounting the PCB. The PCB boards snap into place inside the case and you get 2 mounting holes. This is for some PCB adapter boards I bought off ebay a while ago (33.91mmx41.40mm). They allow 0.8mm TQFP (32 to 64 pin) on one side and 0.5mm TQFP (32-100 pin) on the other side. Search ebay for tqfp adapter and you will find results like: https://www.ebay.ca/itm/2pcs-QFP-TQFP-LQFP-FQFP-32-44-64-80-100-to-DIP-Adapter-PCB-Board-Converter/141975820325?hash=item210e6b1825:g:KEIAAOxyPKNTmAlU:rk:1:pf:0 These work great for my pile of atmel atmegas 128a Designed in freecad. Freecad and STL files included for your torture. Print Settings: It's different for every printer and material used. The pictures shown is my first attempt. As I consider this a tool and not a visual accessory, I print fast, loose and ugly (100mm/s, 0.4mm nozzle, 0.2mm height, 115% feed rate, etc..). You can do better. Note: The pins and pads on the bottom are also attached to the pins and pads on the top. I left a hole on the bottom, so a repair wire/resister could be easily added if required. Also, I'm curious to peoples success's/failures. I can already see differences between the anet a8 and creality cr20 (for better and worse)
